I used haruna and it works. The instructions on the FreeTube GitHub could be clearer though. Depending on if you’re using FreeTube and or the external player as flatpak there are different ways to get it working.

I do the same with moths as they are more active at night

Check out the workaround with an external player. It worked for me during the time friend didn’t work the past few days.

My response to “how are you?” Translates to “preferably well”

You’re not thinking of “pennywise - bro hymn” are you?

From briefly looking over the toot, I think the German version is called openDesk (bad choice as there seems to be some interior design software with the same name) there is a community version you can self host in a docker container. They apparently also have distro packages for Debian and Ubuntu but they seem to have stopped development on those.

Since roguelike is also derived from the game rogue, is simply suggest something like survivor-like. Your suggestion has the problem: not all are 2D, not all have distinguishable waves, and not all are auto shooters :D

Have you checked protondb to see if there are any fixes suggested there? If I remember correctly flatpak steam causes a lot of problems. You could try flatseal to see which permissions steam has, maybe sth is interfering?

Have you changed the steam setting that is should use proton for all games? You can find it under the compatibility in your settings, just choose proton experimental, that should work for most games.
