I'm wondering because I don't want to have to buy the game again just to speedrun it.

From what I've seen the games are the exact same so yes, you can. If there are any differences please tell me, if they are minor enough I'll make a separate category for it in the Misc. section.

The only difference that they have is that Mr Massagy: Mayo Edition is also on Xbox, which isn't included in the devices and it's what I'm using for the Tapless%. It's up to you if you want to make it a seperate category for specifically Mr Massagy: Mayo Edition or if you want to include it in the normal Tapless% run under PC device.

I'll just add Xbox One to the consoles list, if I find any differences I'll make it a separate category.

Great, thanks!
