Game jams are awesome! Even if the game is awful (most of mine are, at least), you still learn a lot about managing a project and getting something from start to finish. Godot is your best bet, it has been used in lots of great indie games (off the top of my head, Brotato used Godot I think), and GDScript (Python with optional explicit types basically) is far easier to approach compared to C# (Unity) or C++ (Unreal)
If you already know how to make nice art/sounds, great! If you don’t, like when I first started, that’s also fine! There are lots of good free assets (see OpenGameArt, Kenney, bfxr, Jummbox, etc.), and pixel art is also fun to learn. I use Aseprite, but any software will do.
I hope Linux is going well for you! Remember that you can easily hop between distros by copying the home directory to a new install.
Nice! Just updated, it’s pretty neat :D
It looks like the system auth Polkit prompt now pops up to unlock the password database (and presumably you could set that up something like fingerprint!)
