Good job on finishing! I didn't notice any major bugs or anything that were obviously unintended, which was nice. The only problem I had was that I didn't really have a way to tell which asteroid would fall down and which wouldn't, so I kept jumping immediately when landing on the asteroids. This may have been your intention, but I personally would have liked some distinction (maybe a cracked asteroid or asteroids of a different color?). Otherwise though, nice job :)
