collision in general is busted and it seems to be impossible (or at least not very clear) to get both characters on a platform. Also, nothing stops you from switching between characters mid-rope swing, which makes for some wild positioning shenanigans.
Kinda. I noticed that and meant to go back and make sure the rope broke but I lost time trying to stop the clipping through platforms (you initially went straight through them if you were swinging).
I honestly didn't think you were being harsh, just pointing out flaws, and that is absolutely fine and to be expected.
The idea is that when you switch one character freezes and the other can use him as an anchor point, it's the only way up to the next platform. I've just done an awful job of conveying the idea (based on the comments).
