How do you create a custom logo for your game file? I see a lot of other games with logos but I don't know how to get it off the default blue cup.
perhaps you lost your way because of the term you used. Don't search for 'logo', search for icon.
There should be a section in 'distributing your game' that talks about "custom icon"
Personally I always rename bitmaps which are as big as icons at a big size. But AGS tells you you can't do that. I'm currently searching for a good icon converter/maker, and I'll post a link when I found a free and reliable one.
