Demon Lord: Just a Block

In Demon Lord: Just a Block, you play as a revived Demon Lord reduced to nothing but a block. On your journey back to the throne, fight, build your deck, and make choices to reunite with your old subordinates, challenge the usurping Dragon Queen Heyla, and uncover the truth behind the Demon Lord's sealing.

This is a Roguelite adventure that blends action-packed combat with strategic thinking.

If you love the combat feel of Hades, Hollow Knight, or Dark Souls — but wish you had a beat to think between moves — this one's for you.

Combat with Zero Reflex Tax

Enemies move only after you do. Every dodge, parry, and counterattack is yours to plan — no twitch reflexes required, but nothing stopping you from playing fast once you've mastered the rhythm. One-handed friendly: four directions is all you need.

Hundreds of Builds, No Two Runs Alike

Wield 14 weapons — from greatswords to laser cannons to your own golden skull — each with its own upgrade path. Draw from 200+ ability cards to piece together lightning builds, turret builds, invincibility builds, shuriken builds, and more.

A World Built From Blocks

Everything you see can be broken. Environments, enemies, NPCs, treasure chests — smash it, move it, use it. Procedurally generated levels keep every run stocked with new hidden rooms and events.

Bosses That Play Their Own Game

Forget bullet sponges — every boss runs on its own rulebook. Learn the pattern, break the mechanic, and beat them at their own game (expect shades of Tetris, card draws, chess, even fighting your own doppelganger).

Dark Comedy, Cute Wrapping

Hand-drawn, colorful, and disarmingly cute — until you notice the gallows humor underneath. A revenge story that doesn't take itself too seriously, but never runs out of personality.

About the Developer

One developer. One computer. One game. One year.

Yuwave builds everything here solo — art, design, code, all of it. If you can feel a bit of weirdness, some dark humor, and the particular stubbornness only an indie dev brings to their own game — that's on purpose.
