updated for android, also linux!

Ok for phones with weird notches shifting the screen around: I had moved the area the game gets drawn on away from the notches but I hadn't scaled touch inputs accordingly so the button positions weren't quite right. It's fixed now!

Also apparently Godot can export to Linux without me having Linux installed so - here's a Linux build. Someone tried it and it works (thanks Lee). I'm honestly pretty happy with Godot.
