So...can I play it with Cardboard? My headset trigger is not really the best, so I end up having to use the Google IO 2016 Headset, but that one requires me to hold the visor at all times (for my own projects, I end up using a BT joypad).
Yes, it's designed for cardboard 2.0 (the one with a conductive button). I've tested it using a bluetooth controller, and the main button (Fire1, likely A or whatever the bottom face button is) works to throw bombs once you're in the gameplay scene. The button doesn't seem to work in the first/menu scene, but if you tap the screen while looking at the start button, it will start, and you can then play with a BT controller. I'm looking into why there's no input in the menu scene. Please email me at email@example.com if you have any other issues. Thanks!
