I think what impresses me most about Sonic Mania is just the relentless parade of new ideas. Each stage seems to introduce one-off gimmicks, sometimes multiple one-off gimmicks, and most of them feel thoroughly explored in their level. Each level also has its own unique boss at the end and its own unique music, and most levels have their own unique backgrounds as well.
Each zone also has unique enemies :V
Yeah, for better or worse that makes Sonic what it is. You don't get as many individual levels as in, like, a Mario game, but no levels will dare show you the same thing twice. It creates a unique sense of progression throughout the game. It's a cool alternative to the level trope-based norm.
