For those who can't install adastra on their Android devices, here is the rebuilt APK I made https://drive.google.com/file/d/17PkrUFXJIYDIIbvFx5fhj36diVuo7Eh_/view?usp=drive...
Edit: The reason why you can't install it because Android 13 and above stopped supporting apps that doesn't have 64-bit libraries. Adastra's Final Release was built with renpy version 6.99.14.2 released on March 27 2018, and that version doesn't build APK with 64-bit libraries included, just 32-bit.
