Fun little platformer. Like Marxy 37, the mechanic of collecting orbs to jump higher surprised me a bit. I thought it would have gotten harder as more was collected. I didn't find this mechanic bad, just different. The movement feels a bit slippery but overall I think the mechanic of the jumping and movements feels fair. The music was pretty solid.
I think my only minor gripes were the blaring bright holes out of nowhere (if I was playing this at night I probably would have had to turn on the lights haha) and a the minor getting stuck on wall moments. Using a different sprite for jumps could add charm to the movement as well.
