TO LOAD THIS in Pico-8 type:
I am not at all certain if Pico-8 runs 100% correctly on Android and cellphones. I would like to think that if it is not, that @zep is certainly doing his level best to ensure that it can.
This program is fairly simple but opens up input, especially for a touchscreen Android and touchscreen cellphone.
I had originally worked this into a complex cellphone driven programming language earlier with 15 buttons in a 5x3 format, but the language is cumbersome, slow, and not at all user-friendly.
So I have put it here. You can test it with the mouse if you like.
6 buttons are already active.
Press (X) by itself to swap between showing the nine buttons or hiding them.
And of course this program is using standard _init(), _draw(), and _update() chock full of remarks to guide you. So you can reconfigure all 9 of these buttons for your use and their definitions and actions.
HOPE THIS HELPS !
