I would give it a 9/10. The game is very very fun, however there are a few flaws. While most of the courses are actually quite well designed and are fair, there are a few that feel like complete pure dumb luck. Slime Climb is one of the most frustrating examples. Often when trying to climb, everyone gets so cluttered that the slime catches up very quickly. Flying Fruit is also pretty much RNG, as avoiding it can be very difficult. Team games are also often uneven. The physics could also be a little refined. Aside from these issues, the game is very very good.
