Clean, simple, and fun ^^ The minimalist artwork is nice. The grid system works well though it can be seemingly random in how the movement range is generating per character, and also it can be confusing as to which one you're controlling if they're near each other (a little player indication / highlight may help). Sometimes I was busted without it being clear why, which may be because the AI calculates the movement and result before it plays out, perhaps you could delay the busted screen so you could see the bust occur?
