Thanks a ton! I'm super glad to hear you enjoyed the game!
The gallery option is actually replaced by the PDF you can purchase when downloading the game! (It's the two "Art of Tomai" PDF's you can see there with all the other downloadables!)
That way, you get all the pretty art to look at, AND you get to learn more about how the game was made and it's characters, AND you get to support a game you love! It's a triple win, imo.
