I really enjoy the green and purple aesthetic. Unfortunatey the controls on this character were a struggle. I'm sure there was some coyote time and jump buffer which helped, but I found that the chaaracter seemed inconsistent in behaviour when wall sliding. Sometimes it seemed like jumping for a wll gave a small amount of height and sometimes it would leap up like a whole new jump.
Also I wasn't sure what the consequence was for running out of time for a portion on the game as I didn't see the ghost, but it also seemed like you had to run out of time at points to cross gaps. That may be me playing the game badly/incorrectly. I appreciate this is a game jam and you were limited on time but it would have been helpful to have some onboarding that introduced those elements a bit more clearly.
Well done, its a proficiently made prototype. With some tweaks and polish this could be an excellent game.
