I think this means I beat it?
I like the concepts you have going here, but the mapping for the controls is pretty difficult to use with one hand on the keyboard and one hand on the mouse. I can see what you were going for, it's just not very intuitive. I like how the grapple is implemented, allowing you to switch modes while grappling, and I also liked the time slow when you open a portal so that it's easier to teleport while falling, and the constant acceleration on the sprint is fun. That said, I was able to complete most obstacles with just the teleport, I'd recommend limiting the range of the teleport to reduce it's effectiveness if you want someone to utilize other tools in their kit. I did not really like the camera bounce on teleport, its a little jarring. Overall, I think your concept is there, you just need to refine it.
