Interesting and unique game you have here! The mechanics where you are provided with a set of different potions with different effects is especially cool, and I could see some real potentials for a much in=depth experience. That's a very good design indeed!
I do have a bit of suggestions that may or may not improve the game, but just hear me out. To me the game seems like more of a puzzle platformer rather than a precise platformer, so I would suggest you give a full list of potions in advance, and let the player decide what's the best course of action. This should makes the game more strategic rather than hectic. I would also slow down everything a little bit, especially the duration of the potions effect. Currently everything seems too tight, and it feels like a precision exercise rather than problem solving.
I also have a game breaking glitch where the player just fly off to an out of bound position and wasn't able to be reset. Oh well.
Beside that though, I would say the game is nicely made. Good job!
