This is pretty good for a second level!
The main issue I find with the level is it feels too straightforward. While there is a lot of stuff to explore, there aren't many actual paths. The large spike balls feel unnecessary for the level and don't add much.
What I did like was the chain mechanic. The issue I have with them is that they're a little crooked, but it doesn't affect it too much.
The gimmick could be used more throughout the stage for different paths, much like how Castle Eggman does it. It'll give it more verticality while giving Sonic more methods to reach higher places.
I'd like to see more levels from you!
I'm glad you enjoy what was there even if it had issues.
Zone Builder is a pain to work with, I'm going to try to learn UZB(Ultimate zone builder). and see if it helps with being able to make my levels a little more creative.
I wanted to add moving platforms above the water in the half way point but didn't know how to make them lol.
Again thanks for the review!
