Click and hold to hook onto a notch, then let go to release. I focused more on the actual physics than it being a game. There are a TON of glitches, though, like how you can sometimes teleport across the top of the screen, but this is the best I can do. Swing across the notches and collect the coins, but avoid getting close to the ground! Can you beat my score of 75?
All the coding is 110% by me. I got the coins from a @griffpatch project I think.
