Well, I gave this thing a quick play through and here are my thoughts.
Sunshine Atoll Zone:
This is your every day beach level, nothing really interesting to say here, save that I found a HoM at one of the caves:
Eruption Conduit Zone:
Okay, I like the new RVZ textures you are using, but the old grass texture needs to be changed. Also, you have a elemental shield right at the start followed by a air shield on a small cliff later on, I think you should swap the places of them. Also, some of the hallways could use a bit more detail.
Drowned Downtown Zone:
This level was okay, but you need more types of bricks, not just adding more stuff TO the bricks. Anyways, I see that you threw in RVZ's water wave, but made it more boring. I also noticed that you stole my idea for a over turned train car. But anyways, the level itself can get a bit dark in some places, like the start of act 2. But other then that the zone is okay, just noting interesting. Also, I like the sector based cones and stuff. :3
Snowcap Nimbus Zone:
N/A
Gritty Columns Zone:
N/A
Fume Shaft Zone:
N/A.... save for the fact you stole my badnik idea. :(
Liftoff Gantry Zone:
This level is okay, not much I find interesting because it mostly uses old gimmicks. Also, act 1 needs a new song for the first outside part. but yeah, not much to say about this level since I didn't play much of it.
Spacewalk Zone:
Ohay, it's a hopping level! Anyways, not much interesting stuff in this level, save with the invincibility laser thing, even though it's just a fancy way at giving them a invicnibility... Anyways I didn't play much of this zone so I don't have much to say about it, save for the fact that I wonder if I'm the only one who likes the song for this level... >.>'
Star Showdown Zone:
loleggrockact3remake. That sums it up, nothing interesting at all about it. :<
---------------------------------------
Over all, you got some okay ideas, but most of the gimmicks are ones from other levels, be creative with your ideas, I know you could do better. Try sitting down some time and writing out a page with gimmicks that you come up with by yourself, I am doing that with Eggmansion Zone act 2. But anyways, keep up the good work, but one last thing. Either redo the match levels or just remove them, all of them are pretty much unfixable IMO. :<
