Mushrooms. It's all about mushrooms. And keys and crates and stuff, too, but really, mushrooms. In Corrypt, a puzzle game by Zaga-33 creator Michael Brough, your job is to work your way through maze-like screens as you hunt for the items you need to appease unsettled citizens. Using a slightly tweaked sokoban-style setup, be ready to sit and scratch your head as you wonder at the logic of carving a path through groups of wooden crates.

It's a perfect example of a simple and compelling little mobile title you'll want to take with you wherever you go.
