Me and my friends have been working on a free and open-source cooking game in Godot in our free time. We’d appreciate any feedback!

There’s no real singleplayer, since the server is required to handle a lot of the game logic. If you want to play alone, you can simply start a local server and join it.
Then maybe a feedback for a future release, just add a singleplayer button that does that in the background so it is clearer for users.
