Lol, i think i found a cheat. Simply don't move at all and you are unbeatable :-D
No critic, but just some improvement suggestions: Guess it would be helpful to also have the description inside the game, not only in the notes, because took a while to realize what is eatable and what is an enemy. Also just saw the possibility that you can shoot a bit later after already played a few rounds.
But alls in all i think it's a real nice game with simple controls that fits the theme and is definitely challenging (as soon as you start moving^^).
