Yeah, I’m playing on an Anbernic RG353P with an integrated gamepad but it’s pretty easy to connect a gamepad to a phone or tablet. There’re even devices like the OUYA, Shield and Fire TV that don’t have any touchscreen input ability whatsoever.
Thanks for pointing that out, I will definitely add these for the next update. The only android device I own is a phone though so this will be hard to test for me.
