Fun little game, but the character is way too sensitive to any kind of impacts. The slightest tap on the head or landing even a bit off and he'll just start to fall over- and nothing will stop it. From then on, you have a short window of time to finish the level or be stuck like in my screenshot, lol.
I pretty much "cheated" through most of the second and third level by spamming the jump key which on rare occasions let me double-jump, and falling through the floor would sometimes give me more height? I don't know. It got pretty glitchy. Jump key didn't respond half the time I tried to use it legit, which is why I was spamming in the first place. I think it could have been good if the controls worked better.
On the plus side, the music was nice and I like the character's design. Good effort!
