Kiwi on Android is a Chromium fork that re-enables extensions on mobile. Works well for userscripts/extensions, though often times those UIs don't scale well to mobile.
Yeah, sure! The game is called Torn. It is a text-based MUD style game. People use lots of tools/scripts when playing it to improve things. Some mobile exclusive users do actually make use of apps like Kiwi on their Android phones in order to install userscripts and extensions. However some people have Apple devices (probably regretably) and as such are limited to less powerful solutions. Luckily someone made Torn PDA [1,2] which helps bridge this gap and give you some powerful tools that you can even use on iOS. If Apple was less restrictive with their browser it may be possible to do more in the browser without needing to resort to these in-app "hacks".
Yeah most people just call it Torn right now, but yeah the game is still going fairly strong. They released a mobile app which helped drive some more popularity to the game again. The mobile app is really just an in-app browser wrapper for the mobile version of their site, but it helped get them some extra visibility for the game via the app stores. Especially with how popular idle style games are right now on the app stores, Torn kinda fits in well with them.
It's pretty neat how long this game has been going for and how they still keep hiring more devs to work on the site! I'm sure if you checked out the game now it would look a bit different from when you worked on it 15 years ago! Though I'm sure some elements would still be a bit similar.
