An edited version of Cat Ninja (a romhack, if you will). Controls are: q to reset crystal count, tfgh to move faster than normal, ijkl to move between levels, z is save, x is load, c is to change level select, v is to go to selected level, b teleports you to boss room, 1-4 are just dumb things don't press them, 9 makes tfgh slower, 0 makes tfgh faster.

I (i) moves the map up, J moves it left, K down and L right. You can't just spam L to move to the next level as some loading zones are down, left, etc.

NEW: Press E to give yourself jetpack in any level
