Hey bro! I just played this, I'm glad to say that I'm much better at the game. This time though I found some game breaking bugs unfortunately.
When I died, for some reason the ball shape got smaller and affected my collision area as well (pic related) - I don't think this was intended, but it made the levels much harder to play due to the ball having less size to climb those slope areas.
Also, in that level where you have to jump to a floating island to push the button (the one I had trouble with last time, not sure if you remember), well for some reason by the checkpoint after that point I died and the player kept spawning below the level making me lose all my lives (I couldn't take a pic as I was dying too fast). It was frustrating to say the least but it's a must report bug issue.
Everything else from what I saw seemed to be working fine.
