Found the answer from Reddit:

"Go to Settings -> Instance.

Choose your Instance or Custom."

Don’t know if it supports Authenticated Mode tho

“While LibreTube only supports YouTube, NewPipe also allows the use of other platforms like SoundCloud, PeerTube, Bandcamp and media.ccc.de.” This was written in their github, Was it added in the lastest update?

Found one via F-Droid

I want to downvote and upvote this comment at the same time

Rust port of the cave story if you don’t already know

(“Cave Story is considered by many as the quintessential indie game because of its one-person development team and influence on the video gaming world.”)

Dicey dungeon

Also you can block in-app ads with stuffs like Adaway if you don’t already know. There are some good games ported in android with shit tons of ads

You can also play indie rpg maker games, haven’t played it much but Grimm’s hollow got a good reputation, I recommend it. You can play this with Easyrpg, But you can find more free stuffs made with rpg maker and run it with Joiplay, MaldiVes etc.

Because you said you are willing to pay There are some good paid indie games here.

This (Also is there a service that audits code’s maliciousness for me? I sometimes use some unfamous stuffs from github for gaming, customizing etc. As long as I don’t give them a root permission I should be ok?)

I asked 😺👍
