That was great. I never understood where I ever got the "P" shaped rock from but somewhere I did. Also the little tiny sparkles were sometimes really hard to see, but that just added to the fun/challenge.
Enemies re-spawning as soon as they were off screen was interesting and led to some mildly frustrating sections that ramped up the difficulty.
I didn't encounter any bugs, the graphics and controls were great with just the occasional weirdness with the double jump.
Great stuff!
