Very unique!! Love the 1 button approach. 
Gameplay reminds me of Mario Vs Donkey Kong: March of the minis.
I think adding some music and maybe some effects could really make this shine.
Would really like to see this expanded upon with a little more polish.

I couldn't get pass level 3, sector A, unfortunately. cant get back on the 2nd platform after bumping into the > right arrow block.
Epic game!
