MouseCraft is a very charming puzzler that could easily be described as some sort of Lemmings light with Tetris elements.
That being said, the game is not of the likes of Incredible Machine or its direct or indirect sequels, where you have to finish more or less insane constructs with switches, rockets, candels and what not, but instead you're exclusively working with Tetris-shaped blocks with different characteristics. Crumble blocks break as soon as two mice walked on them, TNT blocks explode after three seconds as soon as they're touched, goo blocks avoid your mice falling to death and so forth, while the goal is always the same: reach the cheese platter with as many mice - max 3 - as possible while trying to fetch all the Anima (blue, crystaline, floating thingies) scattered throughout the levels.
The levels are pretty short and to the point, the difficulty has a pleasant learning curve and the game has its very own charme from a graphics and sound perspective. The game is not overly difficult, but some of the puzzles will make you scratch your head more than once or twice nontheless.
Over all, I don't regret a cent spending on MouseCraft and am hoping that the devs will continue to build on this promising puzzle game and its odd, but loveable, characters.
