Played it quite a bit, currently on the post-game mode after you complete the main story mode.

- Physics being accurate is awesome.
- Difficulty is good, although bosses could use a lot less HP and some checkpoints.
- Level design is a blast.
- I like the graphics a lot, especially the character models and animations.
- Music is...hit or miss. I actually have no issue with Sonic 4-style music (melody and instrumentation-wise), especially since the melodies are good, but it's weird hearing a mix of that and actual modern-styled music. They really should let go off trying to make music classic, because it's not really working well.

Probably would give it a 7/10.
