Really cool experience. I do wish though that I didn't need to literally click a hand and move it and instead the left/right hands were bound to left/right mouse and then balanced accordingly. You could probably climb really quick but it might feel really cool that way, I wonder..
Loved the powerup themes but think there should've been more negative blocks, and like ol' Dave said below, red should really be used for negatives, I actually avoided them all game.
"Dispair" semi-death was really cool!
