Nice! I liked the vibe in this!
A few things that could be improved are the collision detection of the man -- It seems like you should be able to cross the bridge with your head poking out above the object. The collision detection behaves as if it is a top-down view, but the art is from a tilted perspective. I think the puch could be more responsive too, I was smashing the space bar and it looked like the guy would puch very late -- some feedback to the player would be good there (bigger visual / sound)
Good work!
