Cool visuals! I couldn't figure out how to move the box on stage 3 though. It only moved the tiniest bit when I tried to push it. Maybe I missed something, but I figured you were just suppose to push it!
Oh, wait I got it working, but it seems it only works for me when I pushed at an angle rather than straight down
This is weird, because the box moves at the same angle as the player when he touches it. Glad you were able to make it work.
Sadly, this trick wasn't quick enough to get me past stage six. Maybe someone else can comment if they have the same issue. Still a cool game
