quoting me: Personally what I'd love to see that isn't on this list is zero gravity and still some kind of door&key power-up. I still think it would make the game so much cooler if you could have a rider find a closed off path and you'd have to go in a different direction to find a key. Would make so many cool layouts. You could also for example make a loop thats closed off and while you ride through it you grab a key and it would open the loop so you can leave it, stuff like that. There's probably many uses. It would just be a power-up that would remove a line you selected. For anti gravity, this would be extremely cool as well and make fresh gameplay sections. Im generally mostly supportive of stuff that will open up new types of tracks to create so those 2 are things I'd love to see added.
