I know of one bad thing where the player gets stuck on one of the yellow platforms, but that can be passed up by quitting the game, and then loading the save. 

I also know that I could use some audio and music. 

Is there anything else that you would recommend?

Here is my game: https://zachcreates.itch.io/ball-of-rage-part2

I hope that anyone that tries my game enjoys it! I know that it can be hard, but please, if you are getting frustrated, take a break.
