Indie studio Crunching Koalas has introduced a game where players pay for the features they want to see next.
It's called MouseCraft, and it's a tile-matching puzzle game that's like a cross between Lemmings and Tetris, according to the developer. Players help mice reach cheese by stacking blocks of Tetrominos to create safe paths. Gamers can play for free and, if they decide they want to pay for the full version, can choose how much to spend and what they want their dollars to count toward.
Fans can split contributions between categories such as "more levels, new types of bricks, and additional graphic themes" and "an online system for exchanging user-generated maps," for instance.
MouseCraft is currently in alpha and is available for PC, Mac, and Linux. It's also a potential release candidate on Steam Greenlight.
