Thank you for the information and thanks for testing!
I like the idea of the gravity-potion but I think then we should drop the double space key activation to stay with a continuous control scheme.
An idea: When you already have a potion and stand next to a different kind of potion, the context sensitive button will change to [Switch potions] and the old potion will be dropped at this position so it can be picked up later on.
Btw, did you gave up on the camera angle change during the gravity switching? ..or will this still be available through the game menu?
Somehow it is still there but the controls won't work right at the moment. It will be controllable by a variable (camera_mode).
