You should make more clear imo that the spring is an object that you should get rid of, because i played for a big chunk of the game without knowing that was a thing, and maybe the player a little bit slower and less slippery because it's hard to control with precision. Also jumping on the spring you're holding is an intended mechanic or a bug?? I'm asking because most some intended mechanic, like the super long grab reach or the telekinetic grab between you and a wall, they felt like a bug to me, but discovered later on that they were intended... Great game btw, is really fun!! Good Job!!
PS. Reading the other comments, i just want to say that i'm also a huge fan of Celeste =D
