Hey! Thanks so much for playing my level! Your feedback means a lot to me, even if most of it was quite negative. Lemme address it quickly:
1. It seems the gimmick with the black holes was counter-intuitive for you to understand, despite the given explanation. But don't worry, that's on me as I realize now I could've explained it much better. But believe it or not, the gimmick isn't random. You're actually supposed to go through the ledges if they move in the same direction you're gonna go to get through the solid walls.
2. Thus, with the first point, the second half is not really random. And there's actually a second checkpoint at the second half, but it might not immediately noticeable as it's actually a few screens at its beginning... again, my fault.
3. Perhaps you might be right about the hidden P-Switch, but I thought you might notice it anyway because some pixels of the springboard can be seen. Plus, you actually missed the second Dragon Coin since you're supposed to press it at the cloud ledge next to the hidden springboard.
4. I thought the small on/off switch puzzle was obvious enough? If you actually go back to the very left of the first screen, you can make the line-guided platform respawn. Guess you noticed that, but it seems you couldn't quite figure it out. If it's unnecessary, I'll remove it.
I shall improve my level ASAP before the deadline. Again, thank you.
