isu will release 'GRID CRYPT', a top-down grid puzzle game, on Steam and itch.io on April 23, 2026. The game is available on PC (Windows) and offers a dense puzzle experience completable in approximately 2 hours. Price: $2.99.
●Key Features
Freedom to Choose Your Approach
Read the movements of enemies that react to the map and your position, then aim to wipe them out or reach the next stage.
Eliminate every enemy on the floor, or take the risk and push on to the next stage — the choice is yours.
Trial, Error, and the Joy of Discovery
The key to mastering GRID CRYPT lies not just in learning enemy behavior, but in uncovering the hidden logic of each stage, map, and the dungeon itself.
A Compact but Deeply Satisfying Puzzle Experience
Over 70 stages await, along with a surprisingly chatty Demon Lord lurking in the dungeon's depths.
Estimated playtime: approximately 2 hours.
