i'm not able to change the pause key and i'm just wondering if there's a reason?

also one more question: if your run ends before kai tak, do you have to setup the skip again?

You have to change the secondary to change pause, if that's not the problem I don't know how to fix it.

For kai tak you pretty much can't finish it more than once with the save/load on so as long as you don't go there with the glitch active you're safe. Otherwise you need to restart the game and activate it again. Hope this helps.

It indeed did. Thank you!
