Very original concept, I managed to make the upwards loop but the downwards one I have no idea how it's done! I think something to be improved is the UI of the speed collectables, I didn't know they were collectables until I read it, also the first runs I kept missing the platforms, specially the ones before the downward loop, they could be more visible. Overall I really had fun and good job on the random generation, it really adds a lot to the game
