Also check out meshcentral. Important thing aboout meshcentral is that it lets you hijack the users screen, show you can show them step by step through things. RDP doesn't do that, it kicks the other user out.

Edit: someone already posted it somewhere is in the thread lmao
No, because proton is not Windows. Wine only works on Linux, so it's actually a Linux platform. I consider every developer/publisher who targets proton to actually be targeting Linux, rather than windows. Every single time a windows update breaks something that continues to work on proton I laugh

Yes but the steam runtime is basically an entire Linux installation (that never gets updated) that valve drags onto your system. I found it greatly annoying when I wanted to use Steam Input (because that would make Nintendo Switch pro controllers work) on a laptop with 32 gb of storage and steam dragged along 4 gb of ubuntu that I was never going to touch (since I was playing games outside of steam using wine directly).
Hmmm. What about converting epubs to audio files and then speeding them up? You could do this process on a computer, or probably in termux on the android device.
The most common alternative I have seen is a massive underground labyrinth. But that's really just one big, linked (sometimes alive) dungeon.
For something actually unique... hmmm.
What about subworlds? A "main world" can invade weaker planes of various sizes. The big thing about subworlds, is that they are entire worlds, with living sapient inhabitants. Dungeons and towers sometimes don't have any sapient inhabitents but boss monsters and the "players".
Some tower fantasy manhwa have each floor with sapient inhabitants, but I would argue that subworlds are different, because subworlds can't interact with eachother the way tower floors can. There is no "higher floor power puppets powers on lower floors" because subworlds can't talk to eachother, other than the most powerful worlds which wield dimensional transportation magic/technology.
The other interesting thing about subworlds, is that you could have them have unique magic systems per subworld, forcing adaptation from the main character. Characters could also bring some of this special magic back to their main world.
So, my high school used to have a domain/ip whitelist. The trick to get around whitelists is to take advandage of the fact that whole subdomains or cloud providers would be included in the whitelist.
Any duckdns subdomain, or anything hosted on many cloud providers would be unblocked.
So holy unblocker has a one click deploy, which can deploy to PaaS sites which would usually have their entire ip address space and subdomains included in the whitelist.
Xbox games are actually windows UWP apps, which is the format distributed by the Microsoft app store. Windows games from the MS app store are UWP as well. Xbox's are actually Window's PC's, and have been this whole time.
But now, xbox is releasing a new device that is not locked down to shit and allows you to use some more of it's full capabilities, and they act like it's some hot new feature. I'm so fucking fed up of corporations forcing locked down shit on us and spoonfeeding us unlocked stuff and then expecting us to fucking worship the ground they walk, all because they deigned to "allow" us to use the devices the way they should have been usable from the very beginning.
Yeah you want the titanium networks projects, which are essentially a bunch of web proxies exactly like what you ask for.
I used to use Metallic, but it's not actually that good and not maintained anymore.
Here is a public instance of holy unblocker: https://uc.robby.blue/scramjet
This is one of their flagship projects, and is what you want. Self hostable of course, code on github. I preferred the projects that give you internal tabs though, like hypertabs or anura.
Public anura instance: https://anura.pro/ (but anura looks like a pain to self host, it's much more complex)
