I loved this. The designs are amazing. The concept is cool. The birb is kinda slippery at first but you get used to it. Also the birb gets stuck in place sometimes when the boy travels with the block underneath. One thing I wish you did was make a segment where you make the boy jump on the rat, then make a rat jump while the boy is in midair and make the boy jump even higher jumping off the rat. Overall great game. Well done.
