It's a pretty nice level for the most part.
I like the idea you're going with- But maybe try adding more obstacles instead of enemies.
The maps seem very open and just uninteresting compared to the others-
And the areas are flooded with enemies, which just makes it feel a little unbalanced.
Not to sound harsh, but the levels themselves look like they're in really early betas. There's not much too them. There's too many wide open spaces in my opinion.
The Boss area is actually nice.
It's a little small for me, but I like the little "hiding area" that was put in, and I like the ledge you can climb to knock Eggman down, in case he flies up too high.
However, The biggest problem I see with the wad right now is that the first level is virtually impossible for characters like Amy and Silver since you NEED spindash in it.
Maybe there was another path that I missed but from what I played there is no other way around the level than using spindash and putting in an area that needs spindash will really draw away from the playability since, like I pointed out, characters like Amy and Silver don't have a spindash.
But, again, Maybe there is an alternate path you can take that I missed.
