This feels really unpolished, but it's amazing that you put a whole game together in just 48 hours! The jump itself feels really floaty, so thinking about how high it makes sense for a character of a certain size to jump could help get the right feel for that. Also, I tried walking on the ground around the side of one of the walls, but I was blocked by an invisible wall even though it looked like I could still walk forward. If you don't want your player to go a certain way, put an actual wall there and get rid of the path too because otherwise it breaks the immersion of the game!
