I really enjoyed it! The animations in particular were delightful. I do wish that you could toggle the tiles to a third state to indicate that you know there shouldn't be a banner there, to make it easier to remember what you know.
Thnak you, Bro. I totally agree that I've should put more tile states that enchance the gameplay and make the game more accessible. In my original idea (i.e. when I was thinking, I had a lot of time), I thought about more types of tiles, like dragons and wastelands to make the game more interesting.
