I went as far as Suburbia 1, stopped when I got to the puzzly parts. I see you got a lot of feedback already so I might be repeating some stuff but here we go anyway:
- Recovery time after crashing is a bit too long, breaks the pace a bit
- I would prefer if the ATV kept rotating if I keep holding the button after jumping off a ramp, rather than having to let go of the button and press again
- I stopped at the puzzly parts for a reason, I'm not a fan of having to press buttons to open doors and backtrack in what is clearly supposed to be a speed platformer
- I felt like the maximum speed never really "got there" if you know what I mean. It feels like a cozy stroll even after hitting the speed object. Though this could be partly due to lack of juice as well - definitely could use some particles when going fast
- Objects should be used automatically rather than with Ctrl, I think it would let you design levels better as well. You might want to keep it manual to give the player a choice, but your level design doesn't do that - if I fail to press Ctrl on time and don't get boosted and as a result and I'm forced on a different path with less food, that's fine, but right now if I miss the button press I just have to go to the left a bit and redo it because there is no other path
- I think at maximum speed I should smash through deer and birds rather than getting slowed down by them
Overall it's a fun concept and could be shaped into something great, but I think the level design holds it back for now
