Regarding the performance, it's way better on the desktop version as we actually get more than one CPU thread which matters in this game. If @moralywrong hasn't uploaded desktop builds when I get off work I will.
I personally run and developed everything using EndeavorOS (Arch basically) and it ran fine for me using latest Firefox Developer Edition (can't recall exact version). Though I have a pretty beefy computer. I will try ungoogled chromium as well after work out of interest.
