Great game! I love your incorporation of the theme into the games as car through rings of power.
The car speeding through the cityscape is really cool and I love the experience of it. There are numerous paths which all lead to the goal, and I think that is fantasic, there are one best way to go through.
The acceleration and turns are also great, the car feels hard to drive going through the ring's acceleration also bring nuance to the player choices (going fast through a ring or go steady.)
And great job on making a multiplayer game in 48 hours. Honest extremely impressive!
However, there are a few downsides I want to point out.
There are no map or clear indication of where to go, which can easily lead to the player being lost. I lost my way 3 times more often than not.
The monotonous map doesn't help either, as I am quickly confused by the layout of the city.
The car breaks function too well, even after going through the ring acceleration, which also make the game a tad easier, as you can avoid going off track.
Overall, a very fun game, I would love to revisit it to check out all the possible path in the city. 8.5/10!
