I love this game! Got to the end (yay!), perfect little project. Simple easy to understand controls and the level design acts as perfect self-fulfilling tutorial. I wanted more abilities so I could keep playing! Great game juice.
I forgot to add how good your levels were in how they required the use of power combos (did I mention I love your level design? =) A small tweak I'm sure you're aware off, would be for the punch/extendo-arm to stop at the wall instead of going through it/full length. But the game is almost perfect!
