I have discovered a game-altering bug for macs. Whenever I try to change the options an error occurs and says this: Error: EROFS: read-only file system, mkdir '/private/var/folders/r2/mst29vb11d51d913w710qxbh0000gn/T/A-Translocation/A036E7A5-852F-418C-ABA4-AB4070330F0E/d/Game.app/Contents/Resources/app.nw/save' I don't know if this will help cracking down the save feature but glad to help anyway.
