Really nice entry!
I liked the fact that you can consume rocks and change the map situation: it makes the game more strategic! (I also must confess that it took me a couple of days before realising that green stones weren't edible cabbages and should not be eaten... ^^)
Hoping to give you some useful feedback, the controls seemed a bit off sometimes, and the characters wasn't responsive enough when I pressed the keys faster. Anyway, it's a small thing!
Congrats! :D
