This game is a blast, I love arcade racers and feel like it's hard to come across good ones nowadays especially good ones that are free to play. The flying/wall riding mechanics allow for some fun track designs and add a lot. Soundtrack is on point and is full of bangers.
Despite all that though, I can't shake the feeling that this would have been better fleshed out as its own game or at least that it isn't too fleshed out yet. It has a lot of potential, but it currently feels like a sort of early access - I guess time will tell. That only makes it suck more to see it with the least players of all the new gamemodes, though.
