The actual implementation of snapping between different rails was quite good. Sometimes even I was unsure if she could manage to get there but somehow she did. Reminds me of older Sonic games in that regard. Attacks was a nice addition to change things up a bit, and adding more rails really helped sell the overall feel of the game too. Only problem for me was the controls sometimes lagging behind a bit, but it's honestly manageable once you get the hang of it. Maybe you could gain even more speed later by doing certain tricks.
