Art and music are amazing. birds sometimes merge with their surroundings making them difficult to see. I would diversify the types of hurdles. Separately, I want to note that I liked the dude's pose when he sits, he curls up in a ball :D

Nice art, its difficult to handle the reverse controls at first but its rewarding to pass those dang birds.

I made a similar game, but without the flip controls (or crouch) nice touch on that.

Lovely art and use of music! The gameplay works quite well, and getting caught up on the controls got me at least five times. Nice work!
