You should really put a tutorial or an explanation in the description, because it is really hard to understand what's going on.
Nice concept, but quite hard to grasp
Nice game, simple idea but well executed :)
The game could also use a bit of music, it feels a bit empty by moment; there is a lot of free music on opengameart.org that could increase the feeling of the game ;)
(also, and just for this jam, there is a problem with the 64x64 pixel limit; the player use sub-pixel rendering)
