well well well what a lovely platformer. I looked over your post jam changes and they all seem solid. If you are going to go with random damage ranges I would suggest highlighting the different damage amounts in some way. Damage numbers are an easy go to but you could also do different sounds or effect depending on the damage amount. I don't know if you are aware but your 2nd moving platform can launch you pretty high. Might be a good opportunity to lean into that behavior and build some level elements around it. All in all a very solid game.
