This was a nice idea, I really like the idea of having to swing around normal environments as something small, I'd love to see this be explored.
Unfortunately, the game is super easy to cheese. I didn't have to swing around on all the hooks and things because I could walk on the ground, climb up the wall, and then attatch myself to where to the goal.
Maybe if the ground was an instant loss, this would work a lot better.
I will say that when I decided to not cheese it, it was pretty fun swinging around.
