Demon Lord: Just a Block is a roguelike tile-based game. Developed and published by YuWave, Demon Lord: Just a Block was released on April 29th, 2026. Players play as the Demon Lord, a skeletal being who was defeated by the Hero and was left as just a head. Gameplay is a mixture of both an action roguelite and tile-based strategy. The world, including enemies, only move when you do. This allows players to have complete control over how they play. Whether that be a slow and methodical strategy or a swift take down on the enemies with precise maneuvering, both are viable ways to play.
Demon Lord: Just a Block is easily a game I’d spend hours playing. I am a huge fan of action roguelikes such as Hades and [REDACTED]. Though my initial belief was that the tile-based gameplay would hinder my enjoyment, I was quickly proven wrong. There’s a reason for the game’s overwhelmingly positive reviews on steam. From the graphic’s whimsical charm, the unique builds and weapons, and amount of variation from one run to another, there are a ton of positives here. The few ‘negatives’ I do have are only wishes for small improvements. I was easily entranced by the game and fell into the mindset of “one more run” for hours. For me, this makes for some of the best roguelike/lite experiences. So, keep an eye open for Golden Skulls, because it’s time to discuss Demon Lord: Just a Block!
The Demon Lord has been Defeated
In Year 159 on the Sacred Calendar, the Hero has slain the Demon Lord and emerged victorious. The people cheered and celebrated. The evil beings in the world fought for the Lord’s chair, their position of power. However, unbeknownst to all, the Demon Lord clung to life. Reduced to a lone skeletal head and robbed of their past, the Demon Lord nevertheless hunts for revenge. The Lord hops off of the throne in an empty castle. This room serves as a central hub for between runs. Any time you’re defeated during a run, the game sends you back to the throne.
Along the way, the hub comes alive as players recruit allies and find new weapons. The Demon Lord’s loyal followers, such as Lulu and Murphy, help with the Lord’s adventure, providing the roguelite elements that make runs slightly easier each time. Lulu is responsible for the Demonic Pact. After completing a stage, a common reward are souls. Players can collect souls to spend in the Demonic Pact book to purchase passive effects. These effects include things such as increased HP, increased damage, and guaranteed occurrences in a run such as choosing an ability early on or unlocking various areas. After maxing all the upgrades on one level of the Demonic Pact, the next level will unlock, up to level 6. Thankfully, Lulu gifts a decent amount of souls to help you in the beginning.
The Demon Lord has 14 weapons at their disposal, but players need to unlock each one first. Murphy, the blacksmith, can provide powerful unique effects for each weapon during runs, depending on which one the Demon Lord chooses between runs. Some of my favorite weapons are Lightning Chidori and Shadow Dagger. The Lightning Chidori allows you to dash through enemies at lightning speed. Some of Murphy’s upgrades for this weapon is a massive increase the dash range as well as the damage based on the range. In short, it was a lot of fun clearing a long line of enemies with one fell swoop. The Shadow Dagger does increased damage with backstabs. Some of Murphy’s upgrades boost backstab damage and make flanking attacks count as well. These made me feel like an assassin, dodging away from attacks with heavy hitting blows to the enemies side.
Another between run aspect are stickers. Stickers are collectables that offer powerful effects. For example, the Murphy sticker (probably one of the first players will unlock) guarantees a blacksmith encounter at the start. Only one sticker can be taken during a run, with more unlocked in the Demonic Pact. These will play a bigger role later in the game as you progress. Outside of stickers, there are a few other things players can do in the castle. There’s a training dummy who threatens you. There’s your collection of Golden Skulls, rare and hidden skulls found during runs. There are also setting options, such as changing the difficulty (9 total levels) or changing the Lord’s and castle’s appearance if unlocked.
Overall, I have almost no complaints with the hub. It is a standard roguelite set up that works well and can be navigated with ease. One wish I have is with the weapons. Each time you are back in the castle, a new weapon will have a soul gain, increasing the amount of souls you receive by 50%. However, this seems tied to the stand the weapon sits on rather than the weapon itself. When you swap weapons, the game places the weapon on the new stand instead of returning it to its original spot. If you swap a few times, or walk away from the computer and come back, it can be easy to forget which has the soul gain benefit since the icon stays at the stand. Ideally, it would disappear, or when swapping, weapons would go back to their original stand instead of where you place them.
Another small wish I have is for more customization options. There are currently three options for both the Demon Lord and the castle, with one being in the purchasable supporter pack. I’d gladly take even basic color‑palette swaps if they were unlockable with souls.
The Demon Lord Seeks Revenge
At the end of the throne room’s corridor is a large portal. This is where the runs begin. Runs are of course procedurally generated so that no two run is exactly the same. Players start in Darkwing Forest and will need to make their way through each stage to proceed to the next area on the map. The world is a tile grid. As mentioned, the world, including enemies, only move when you do. Players set their own pace—fast or slow—but they still need to think strategically.
There are over 70 enemies and bosses that players will run into. Each enemy has their own attack. Most attacks can be anticipated. A small red arrow on each enemy shows in which direction they will attack and how soon. The enemy’s appearance hints at what it’s about to do, and those tells give you another way to read the fight. Over time, players will become familiar with the different enemies and will be able to navigate around their attacks with ease. For example, a common enemy early on is chompmaw. Chompmaws attack in a straight line and take three turns to perform their attack. However, they still hit me even when I was sure I’d moved back in time. I then realized that they can actually hit a few blocks instead of one. Since then, they’ve become easy to dodge to the side rather than back.
Boss battles are no different, just a bit more complex. There is a large variety of boss battles, each with their own unique mechanic. One of the early bosses players will run into is a spider queen. She can summon spiders, along with the four spider eggs that also summon them, and do a jumping attack. She was quite difficult to beat at first. The stage quickly became filled with spiders, all looking to serve me to the queen. It wasn’t until I become a bit more strategic that I was able to take her down. Honestly, the boss battles are some of the best I’ve seen in a long time. They can get difficult, especially in later stages, but it never felt frustrating. I understood why they bested me and gained experience for the next time. Nothing bogs a roguelite experience more than a frustrating boss fight.
Outside of weapons, there are a few combat tricks players can do. Players can dodge and parry. Both actions require players to ‘move twice in one turn’ by quickly moving out of or in the way of an enemies attack. At first, I thought these would be impossible to perform, but they’re actually quite easy. It is simply just knowing the enemy and quickly double tapping in the direction you want to go. These small combat effects give life to the tile-based combat. Players break free from rigid turn‑taking and use these actions to tilt combat toward their advantage. The system surprised me—I genuinely enjoyed every encounter.
Of course what also majorly improves the combat are the items and abilities. Items are one time use and provide effects, such as a temporary invincibility shield or the ability to fly on the current stage. Abilities provide more powerful effects and help make the build you are currently going for. There are over 10 types of builds, but players are not bound to one or another. In fact, there are over 200 abilities. Builds are simply just card types that have the same general effect. This includes different types of ally summoning, fire which spreads and deals damage over time, and shurikens that make your next attack stronger. Abilities can have different levels of rarity as well, with rarer ones giving stronger effects. Some abilities also change how the Demon Lord looks, which was a nice touch.
As is the case for most roguelites/likes, different builds might feel more viable compared to others. For example, stacking lightning based abilities with the Lightning Shidori just kind of makes sense and can easily sweep groups of enemies. However, I personally never felt that one build or another was not viable to use. I never got the feeling of “well these abilities suck” or “I died because of my build”. It is all about being strategic with the abilities you have and how you prefer to play.
Outside of all the combat based stuff, there are a few non-hostile encounters you can have during runs. Some of them will require coins, a disappearing currency you can collect during runs, in order to play. I will say, I did find some of the coin prices to be a bit steep, as I didn’t run into too many early on. It is probably better to save the coins at first so that you can spend a lot at later stages. Some encounters are with Murphy to upgrade your weapon or a statue allowing you to spend HP for extra abilities. After completing a stage, portals to the next stages appear with an icon showing what lies on the other side. There is strategy here of course in choosing one that works best for your current run.
Like with the hub, I don’t have a lot to complain about when it comes to the runs themselves. I love the run variety. A huge downside of roguelites/likes are when runs feel the same. That simply is not the case here. I felt like I was having a unique experience each time which certainly helped prolonged my desire to play. It was a lot of fun testing out different builds and seeing what works best for my playstyle. Even when I felt that it wasn’t for me, I still enjoyed using it. The balance of strategy and action in this game is beautifully done. Again, though my initial feeling was that I wasn’t going to enjoy the tile-based gameplay, that simply was not the case.
Demon Lord: Not Just a Block
Did I mention that Demon Lord: Just a Block was developed by a solo developer over the course of a year? I think the work that YuWave put into this game deserves some recognition. I know they aren’t the first, and certainly won’t be the last, solo developer game I’ve reviewed but the time, dedication and passion here feels very apparent. This game has tons of references to other games. Boss mechanics draw inspiration from classic games like Minesweeper and Snake. The enemies also borrow from familiar titles—the chompmaws echo Super Mario’s piranha plants, and the furious chickens channel the cuckoos from The Legend of Zelda. The whole experience feels crafted by a lifelong gamer who wanted to build something for players like themselves.
Overall, Demon Lord: Just a Block is certainly not just a block. It’s a fun roguelite action game with tile-based gameplay. It has all the best things I love in roguelites with pleasantly surprising strategic twist that goes beyond just running in and hacking away (though you certainly still can). I adored the whimsical art style. I enjoyed testing out different builds, abilities and weapons. Combat felt smooth with a blend of strategy and action. This is certainly one I plan on coming back to and is easily one of my favorites of the game’s I’ve reviewed. I happily recommend giving this one a consideration, especially for anyone with a Steam Deck.
Thank you for reading and now I’m just taking a nap…!
