Bean and Nothingness is a challenging, turn-based puzzle game in which you turn beans into monsters to help you -- but then these same monsters will get in your way.
Each puzzle has a set of recipes -- instructions for how to create various monsters.
As you progress in the game, you'll meet new monsters (and other mechanics); for each monster, you'll have to learn how it behaves in some easy puzzles, and then move on to more difficult puzzles, where you'll have to combine the mechanics you've learned in new ways.
