DUDE! This game strikes me as a majorly psychotic style-overload. Gorgeous visuals, especially fond of Connor's and Lucia's sprites, the music is fantastic (each and every track) and the gameplay is really nice! The shop as progression kept me playing for a while until I had all the upgrades, at least definitely long enough for a game jam entry in my opinion. The ramps are a great way of seperating the track segments and sprucing things up every once in a while, while I personally think the obstacles could be broken once you hit into them, as you could get stuck on a single one for a bit and lose quite a lot of HP - Though this is mostly just a matter of taste, as both ways of executing this mechanic work for the gameplay totally fine.
Great entry! Gonna be bumping the music for a while now hahaha
Edit: And how could I forget the amazing tutorial. That was. Perfect. 11/10.
