I know its kinda ironic to be complaining about my own section, but since the bowling balls work a bit differently from how they were when I originally made it some of the setups don't really work quite as intended.
This one is especially bad because I doubt most players would expect the bowling ball from the left suddenly coming from up high (since it wasn't supposed to in the first place), which can result in unfair hits.
If you want I could redesign the level a bit and send it to you again to fix them.
Now regarding the second half:
No powerups at all.
This ledge feels kinda weird since I'd expect it to have something, yet it doesn't seem to have any purpose.
Having the bowling ball so close to the spring makes the jump kinda uncomfortable, so I'd move it 1 tile to the right at least.
Nice
Also there only four morton coins (I could place the last one in my section if needed).
