I didn't understand what you are suppose to do in the cave-like zone. The fact that the camera moves upwards a lot when you jump makes it a bit hard for the platform parkour too, because it's hard to tell when you're falling.
The game was very unfinished. I worked with a buddy and he was using a different version of the engine so nothing really worked. Sorry for wasting your time. Will play your game to make up for it :)
