You know this is unfinished and extremely buggy. Don't be in such a rush and don't give up. Polish this turd!

It could be the basis of something fun, but right now it comes across as unfinished. The character gets stuck on nothing in mid-air almost every time you try to jump, and there's no indication for when you take damage. The music does get grating very fast. I'd suggest a health bar for your character, working on the jumping issues, and making the levels less bland. Good luck!
