i love the art style and the fast paced gameplay! however
the jump is a bit hard to control, the minimum height when you tap jump is too high (but it feels like it's sometimes lower?)
checkpoints 3 and 4 are kind of a difficulty spike
another thing is dying at a checkpoint is pretty punishing because you lose all the momentum you built up and often get stuck in a death loop because of it, i'd suggest you go the trackmania route and have a little replay of how you got to the checkpoint and carry the momentum from that
if you go on a loop when you're fast enough you just can't stop and go all the way around it which doesn't feel great
i also didn't really find myself using the zap ability like at all, it just didn't really feel like it had a reason to be there for me (though it may totally just be a skill issue)
overall though, i think it's really nice!
