Nice job! I had just a few problems with it though. Wall jumping kind of feels weird and jumping on the moving platforms is really buggy and sometimes doesn't work. I am not sure why, but it also didn't let me play level 2. I tried replaying the game multiple times and refreshing the page but nothing seemed to help. Although there are a few problems, this game was fun to play, which in my opinion is the most important thing. Some games can feel way more polished than this, but if they're not fun, then I am not going to play them for long, so super good job with that. The music was also pretty good which helped it not get boring. Overall this is a decent submission to this game jam. Great work!
