This whole post is so funny, because by reading the comments I think OP tried installing GL Tron of all games and it didn’t work for some reason, spotted that it was last updated 12 years ago and thinks that’s why it doesn’t work on modern phones and now everybody here (me included) is having a great time playing GL Tron on their even more modern phones. 😂
Also this is the exact reason, F-Droid shouldn’t remove apps. Because the algorithm cannot know if the app is just completed and works even 12 years later or whether it’s abandoned and stopped working 2 months later.
Edit:
Just for the record, I have looked through droidify because of their “all apps by last updated”-list and scrolled all the way down.
The “most abandoned app” is Trolly. A shopping list app with too many permissions.
The “most abandoned game” is DroidAtomix which seems unplayable on my phone. The next “better” game is Replica Island which does still work, but is not that much fun to play tbh.
