The PC version is still black but has audio.
Pressing 'A' on the apk version works to select. Maybe I was using the wrong button. I thought I has tried them all.
I got to the Goblin Wood with 40 health and get as far as the spiders before dying. It would be nice to restore health to 100 on a restart otherwise you just go round and round. Or put more health in barrels to find?
Also, I could not open the menu in the Great Tower or Goblin Wood?
