Cool mechanic. The physics work just fine:
But as others already mentioned the problem is with the lag later on that makes it hard to climb.
Very nice game overall and the graphics are neat. Good job.
Yea, I should've probably been a bit more mindful about the performance, we just both have pretty powerful rigs so we didn't really notice (apart from a little collision problem we had where the bullet thingy would fly through half the level and create enormous ropes :<). Could've probably fixed that by just putting a maximum on debris allowed or whatever, but I don't wanna look at the code anymore lol.
Also, I laughed out loud about the gif, that kind of gameplay really wasn't the intention but looks like it works :D
As for the graphics, thank my crazy artist person. We were all like "dark cave, you're a spider type thing, much spooky, very scary" and then suddenly you're a cupcake climbing delicious-looking blocks. I don't know what happened lol. Thanks for the comment!
