So I fell from the screw and can't get up again.
The art is looking really nice but while it's really pretty, it doesn't feel very Sonic-y, it actually reminds me of Kirby a lot specially the backgrounds, and so does the music. (It's not bad music though) Terrain wise, level design is on the right track for the most part, as it has plenty on paths to explore, but there's some spots that really bother me, like the bit near the end of Act 1, where you can run on the water and
there's a wall that stops you, having you go back and get the platforms. It really ruins the flow. Here's something you could do.
There's also the obvious, and that is that there's really nothing else other than rings and springs to interact with, no badniks at all. It feels barren.
Also, the climbing section with the waterfalls and the body of water on the bottom in Act 2 is really annoying, there's floating platforms, some conveyor belts and that's about it. Falling only makes you fall into a boring and flat underwater section.
Lower paths should NOT be completely empty, flat and uninteresting, in fact, not any part should be like that.
There's a lot of potential, just work on those bits.
