Android version has some pretty mahor oversights. On day 7 I trued to serve a drink, realized I had no energy, but there was no way to back out of the drink selection menu. Since I also couldn't select a drink my only option was to close the game.
This was made even worse by the fact that I could not figure out how to save, so it either isn't possible on the version I played (0.3.4 android) or is very out of the way.
