The biggest example where many levels have many stars exists is "ASMBXT: Prelude To The Stupid". Several levels do have many different paths, and each of the paths leads to the leek (replacement of stars here) exit. So, to complete all of them, you have to replay the same level as many times as many leeks it has.
If you want to play this on Android, you can, there is a ready-to-play assets package:
https://github.com/Wohlstand/TheXTech/w ... the-stupid
1) Download it
2) Unpack it into any convenient directory, for example into "TheXTech Games"
3) At TheXTech's launching screen, press the Right-Top icon, and select "Add game...", then select the path to the unpacked Prelude To The Stupid game.
4) Start it.
5) If you want to play normal SMBX and ASMBXT, just use the Right-Top menu to switch between games.
