Hello! I was one of the streamers who took part in Feedback Quest, and I'm here to leave some comments I had while playing.
To start, I loved the part where you had to start by running to get a chair. This makes it feel like real life, where you can try to steal the chair an opponent was going for in order to slow them down. The game also plays how I would expect it to.
When I was playing, I was confused as to what power-ups did. There should be an explanation, either in the race or before you go in, that shares what they all do. Some of them I never figured out what they did.
I would recommend giving the player a mini-map in the corner of the entire race track and something to indicate where they are as opposed to the arrows that indicate the direction to go. The arrows don't adequately prepare you in time with the limited view you have, while a mini-map would allow the player to see well in advance where they need to turn.
