Road to Vostok looks absolutely insane and it’s being made in Godot. I’ve played demos of it a bit and it definitely still is in development but there’s serious potential in my opinion

It performs insanely well, too

so I originally got mine for my PC and that’s where I mainly use it, but I also use it with my Steam Deck sometimes via Bluetooth

I have the Epomaker EK68 and it’s a 65% sized keyboard so it’s smaller than a full sized one but not too tiny. I find it nice because it’s not TOO compact but can slip into a backpack without taking up too much space. It can connect with USB, dongle, or Bluetooth and switches between them with a little switch on the back. It’s mechanical and you can swap the key switches for whatever type you want

Overall not too expensive either
