Assuming you're using the default Ubuntu (the one with Gnome), it's under the display settings and called night light.
I never got into the genre, but in general I just don't really go for competitive multiplayer games anymore. I'll try one every now and then but I don't tend to last for more than a month or two before burnout hits.
I do like playing challenging single player games though.
Minecraft: Both due to nolstalgia, and because it's just a really good relaxing set of albums (the post C418 tracks are also good in my opinion)
Celeste: It's just good and also enhances the narrative.
Everhood: Wouldn't be a good music focused game without good music.
Furi: Listen to/buy the OST if you like synths.
ULTRAKILL: I don't know how the OST keeps getting better with each episode, but it keeps getting better with each episode.
and most recently... Pizza Tower: funky
Thank you for reading me finding slightly different ways to say "it's just good" 6 times in a row.
On desktop there's Freetube, which is an accountless youtube frontend, which I've basically been daily driving for over a year now. It's not the best experience in the world, as it still lacks some features like playlists.
I tried using Comic Mono for coding once after seeing this video about Comic Code. Honestly it was a pretty good experience.
My guess is it was the situation where DDG couldn't block Microsoft trackers in their tracking blocker applications (their browser and browser extension and not the search itself), because of the contract they had with Microsoft to use the bing search index for DDG search. I believe the problem was resolved, and never affected the search itself.
Minecraft mostly. I have a group of friends I play with in multiplayer that tend to start a new server when a new version releases.
