I tried creating a game where you can change gravity while still having a clean platformer my idea was to make it a VVVVV concept. A/D move left and right NO JUMPING W to switch gravity
As of now I don't know how to make it only let you change gravity when you are on the ground so right now if you hold space you slowly fly up/down depending on your gravity If you can help please do as it will really be useful to know what's good and bad. If you do help Ill put your username in the next version.
