This pack blew my mind playing through it, because of how you managed to perfectly capture the essense of the original stages using strictly vanilla assets. These levels don't force themselves to be Another Game But In SRB2, they're not 1:1, but adapted very stylistically within srb2s vanilla texturesets.
There's a lot of jank in this pack when it comes to scale and flow, but that's just because modern sonic level design doesn't always lend itself perfectly into SRB2s controls (without adding custom characters, that is). And there's a bit of editor jank that I assume comes from learning the program as you go, but as it stands these are extremely well crafted levels from a zone-builder standpoint, and I was very impressed by a lot of the structures.
Great job, looking forward to where you go from here. Welcome to Releases!
