Obviously I can't compile the game on Android, right?
If you've installed both a bash-compatible shell terminal and tweego on your android device, you should absolutely be able to build just fine, similar to how you would on linux. I think termux is bash by default, so basically:
1. Install termux from the Play Store or whatever
2. Run
pkg install tweego
from termux, and make sure that running
tweego -v
outputs some lines starting "tweego, version 2.1.1+...." or similar.
3. Extract the pregmod source zip, or
pkg install git
and clone the repository the usual way.
4. Run
./compile.sh
from the root directory of the source tree.
If messing around with a terminal in android makes you uncomfortable, then no, you can't compile the game on android.
