Pretty interesting concept! I like how you can see which shape youre supposed to be just by looking at the environment lol
Some things I'd like to see changed is the way the camera works, it's a bit jumpy... I think the camera should be further down as well, because being able to look up is kinda pointless because you don't have a way to go up, also when youre a flat line you can fall off the stage really easily lol
But I like the concept, it just needs some polish
