Here is the full feedback (WARNING, Big Post!):
IV: I like it, but I think you should get at least SOME coins.
V: I don't the amount of straights in this.
1 & 2: I like the levels, but they could better textures.
9: The rainbow glass doesn't fit with the background
10: Extend the time, otherwise it would be impossible to grab all coins. Chalk texture doesn't go well with bg either.
12: Add some coins.
14: Add some coins and obstacles in marble - light and turf - purple floors to make them more exciting, otherwise, their useless.
15: Add a blocker to the second timer until the glass box is done moving because when you hit it too early, then it won't move and you have to wait to activate it again.
II, III, IV: Don't really like these levels much.
6: Add some edge - orange and coin- orange textures to make the level look better. And smoothen the curves too.
7, 11, 12, III: Add some more coins to them to them more fun.
8: I think the platforms move a little too fast; especially the second set.
13: Don't really like this level. The textures aren't use well, and I hate the big bounce at the end.
15, 16: Don't like these either. The platforms move way too slow especially in 15. There's nothing much to do in them either.
18: There's too much stairs.
19: This level gives me a LOT of trouble. The rotating bridge should move a little slower so I can see where to stop it.
20: Too much straights.
IV: I agree with CH Mod 700. Add a counter for big laps.
V: The purple spiral is way too long.
2: The blue platforms move a little too slow.
9: Not much to do in this level.
11: The fact that this is Extreme IV, auto levels like this shouldn't be in this set.
14: I appreciate the revival, but I didn't like that you removed the coins.
V: The moving plus sign takes TWO MINUTES to get to the destination.
That's all, Your levels are amazing!
