Great Idea, but flawed
I really like the idea for this, sure the animation isn't great and it's not that long, but it's nice to just have a fun little stint with unusual but fun controls.
My main issue is that by pausing every time a move has to be made, you're slowing the gameplay down and it seems stilted and unnatural, which is the opposite of what you want parkour to be. If you made the rest of the game more like the end sequence, then I think it would be a great improvement.
