Checked by myself
Okay, so I discovered the following:
1) Official game on my own, NON ROOTED real phone device does NOT reset your progress
2) Official game on my ROOTED LDPlayer 9 instance DOES reset your progress (It detects the root)
3) Signed Mod on my ROOTED LDPlayer 9 instance DOES reset your progress (It detects the root)
4) Unsigned Mod on my ROOTED LDPlayer 9 instance straight up force closes
5) Signed mod on my own, NON ROOTED real phone device does NOT reset your progress
6) Signed mod on emulator with the mod features DISABLED DOES reset your progress
So it seems that the game just straight up detects root/unwanted applications and then just won't save your progress.
