Hey wow, thanks for the review! I'm hoping in an update coming soon to start introducing tile sets, so that people can have multiple different graphic sets to choose from. I'll probably start out with customizable backgrounds.
Claustrophobia Lite is also coming for people who wish to preview the game. Unfortunately every time I make a release I forget to make "Allow Tapping" on by default, so I'm hoping this doesn't deter people from playing!
