Because TIC-80 can't export Android builds atm, it's a bit tricky, but possible! Note however that because the game is not optimized for Android, FPS drops are common (especially when scanning).
If you want to try it out anyway, here's the instructions!
1. Buy the PRO version of TIC-80 (it's $5). Download and install the apk for your Android device (you have to allow installing from unknown sources in settings).
2. Download the .lua version of EMUUROM demo and move the file to TIC-80's data folder. For me it was located in /sdcard/Android/data/com.nesbox.tic/files/TIC-80/
3. Open TIC-80, and type in the following commands:
load emuurom-0.1.i.lua
run
And you're good to go! Bluetooth controllers can be used to play the game, but onscreen controls are also available.
