I produced my first Steam game entirely with AppGameKit! I originally started it in AppGameKit 2, then switched to AppGameKit Studio when it became available earlier this year. I actually released it two months ago & just recently realized I should probably post about it here.
The game is called Dum-Dum:
It's a comedic adventure/puzzle game that simulates a fictional computer OS from the 1980's. Players must dig deep into this self-proclaimed "greatest operating system of all time" to unravel an epic story, solve puzzles, interact with quirky characters, and ultimately save the world. Or they can ignore the world saving & explore many bonus activities and mini-games in what is essentially a complete functioning old-school operating system.
Here's a game trailer done in the style of a 1980s-era commercial for the operating system ("Hogo OS 1985 Edition"):
