Thanks! I would like to port it to Mac in the future, but it will require moving it to a new engine, so it will be a while.
Ooof, I didn't realise Gamemaker can't export mac builds. If you do decide to port it, godspeed! In meantime I'll track down a PC :)
Old Game Maker versions can't, but GM: Studio can, however, you need a Mac computer, too.
Yep, exactly. I would like to port Cthon to Studio down the road, but there's a lot of stuff that will break that will need to be fixed, so it will be a fairly major project.
