Just configured Godot to be able to export to Android and made and uploaded the first Android build of the game. I've only tested it on my tablet, but seems to work fine.

Update: I just noticed that the particles (the snow in the background and the fireworks in the perfect message) are missing in the Android export, at least on my tablet. I've tried to make a version using CPU particles instead of GPU particles if the GLES version is not 3 (which was what I thought was the problem) but they are still not showing, will have to think a little more about how to fix them.
