I downloaded on my Galaxy 7 will start up but then just stops and goes gray screen after the company title screen.
Edit tried on kindle fire same issue...
I'm working on the issue right now. Seems to only be the android version doing this. I'll try messing around with settings and updating my Android software to see if the problem comes from some random setting in Unity that changed since the last Demo upload.
But for now, the other versions seem to work just fine. Hope you can play one of those in the meantime!
