Hi I started playing the game on mac but the game goes full screen and I have a 32" 4k monitor so it looks really bad, I want window mode. Also I had to turn off my computer to exite the game. Couldn't find any option or setting menu and I pressed all the keys on my keyboard to no effect.
Does this game autosave? or can I manually save too?
Help please.

You can switch to windowed mode by pressing option-return.

You can access the options menu by pressing fn-F5, this menu has save and quit options as well.

Note that the windowed mode is not resizable, if you want a proper window you should download the full version SCUMMVM and play the game through that (the GOG version of this game uses a pared down standalone version of SCUMMVM which is not full featured). https://www.scummvm.org/downloads/

Awesome, thank you so much

I installed scummvm and then i have to "add the game" to the scummvm interface. I tried every directory in the game and none of them are being recognize as the game. Any directory I should be pointing at?
