I love the twist on the classic racing game! This is a really fun multiplayer game.
I did run into a small bug while playing with my friend. In the player lobby, some of the text didn't appear correctly, although the game itself worked fine.
The boss fight was also really fun! I think the laser beam could use a small adjustment, though. Sometimes it spawns at the same time as the regular attacks, leaving almost no chance to dodge.
It would also be great if the progression after the boss fight was balanced a bit more. I found myself becoming a little too overpowered after getting the upgrades, which made the later parts of the game feel much easier.
