a few things:

-Your game would look more appealing, if you add some screenshots to your itch.io page

-in my opinion, you should have a little control overr your jump (press for a short amound of time to jump lower, press longer to jump higher) cause i think it would feel better.

-in the moving platform level, the platform should move the player, so it dosn't slip away beneath you
