A pretty fun idea and a fun execution! I ended up playing for a good amount of time for a game jam game - I do think that the game gets pretty fast pretty soon, which can make it hard to move all the obstacles out of the way in time, especially the smaller ones - maybe you could've added a slow-motion button that can be used for a limited time? I do with there were more types of obstacles apart from the pipes and spikes (there might've been more further into the game but I didn't see them), but with a limited amount of time, I understand why there aren't more. Overall, very clever idea and a fun little score chaser!
