MouseCraft is a puzzle game that combines the mechanics of Tetris and Lemmings. The game features 80 handcrafted levels where players help Schrödinger, the cat scientist, in completing his mysterious, mice-powered invention. The goal is to pile up Tetromino bricks to create a safe path for as many mice as possible while gathering collectibles, fighting enemies, and avoiding environmental hazards. The game also includes a level editor that allows players to create their own maps and share them with the community.

The game features seven different types of Tetromino bricks, two types of environmental hazards, bombs, and enemies. Players can use different types of blocks, including explosive, crumbling, and jelly ones, to defeat obstacles and overcome gaps. The game also includes a feature called Active Pause, which allows players to freeze the game and increase the speed at any time. The soundtrack, composed by Mikolai Stroinski, adds to the game's charm and overall experience. MouseCraft is a fun and challenging game that provides about 6-10 hours of gameplay and full Steam integration, including Cloud Saves, Achievements, Leaderboards, and Trading Cards.
