It's strange. Normally, you should double-click on the desktop icons ( in the game, not in Windows :) )
All interactive elements place mouse in pointing hand icon.
It's the double-click factor. You might want to mention that you have to double-click icons, in the game description.
I had a similar issue, until I started spam clicking, and figured it out.
Okay. I will add something like a tutorial notification when you start the game for the first time
I'm surprised you replied so fast, but that's good to hear!
ive tried that obviously... double clicking all icons besides quit dont work
