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.
