I really enjoyed parts of this game, and others really frustrated me. I was having a lot of fun on mindless romps through levels when the stakes were low. The cop level too was very fun, up to a point. The rails don't really seem to have much player forgiveness -- there's really not much of a way to control what you want to do on them. Sometimes the balance will flip instantly and you're left careening into some spikes. Other times, you'll hit a rail the wrong way and fly backwards. The giant spike wall was quite frustrating.
I think the section before the cop chase and the very first section of the cop chase were my favorite parts of the game. The spring really opens up new movement options and adds a new layer of complexity to the gameplay. QTE chase events along unpredictable rails aren't quite as fun.
Really has a lot of potential if these small issues are ironed out.
