This game looks great! And the start screen looks great too! The gameplay is great, it’s unique and sorta sweet especially considering your motivation behind the concept.
I agree with the others here that there should be some sort of indicator to help progress. Although, I can claim victory as I beat the game :)
I think you should at least put in the description, the fact that the characters are able to move. At first I thought it was a bug!
Overall though, great stuff, I hope your girlfriend thinks so too!
