Sweet parkour game!! It was fun. As someone else mentioned, the first teleporter one was a little confusing. Also, it would have been great to make have the cursor hidden since the mouse is used to rotate the camera.
Also, did you include a network multiplayer feature? If so, I have no idea how you did that, but that's awesome. Even if you didn't fully code it and it's just for appearances, very nice touch either way. And I liked how you kept the game simple but with an effective concept.
