Had a blast playing this one! This feels so premium and well thought. Navigation is smooth, everything is easy to read.
I also loved the art style and the music is perfect for this type of game. I honestly wouldn't have been shocked if that was a game I paid a few bucks for. With more content and variations, it could easily be a release I would buy!
Also, adding the hints.txt was a nice touch. Game isn't that hard but I like the fact that you can get some clues if you need.
Congrats!
