Not on steam, but PokéRouge is my current addiction
If you know where to look you can get a high end bike that was unfinished at the factory and didn’t get painted/stickered/branded and pay a fraction of the price.
Can you tell me where that is?
If you talk about a physical keyboard that is plugged into your steam deck: have a look at eurkey
I think your problem is that you installed the Emacs “plugin”, but that is just the interface to the server. I think you need to install the actual language server on your system. Outside of Emacs, in your package manager or with pipx for example.
You can also try to press Spc-: and then run lsp-install-server inside of doom Emacs, but I had problems with that.
