I love doing logic puzzles, so this is a no-brainer, but I really loved this game! The overall aesthetic and the music was very calming, meditative even. As someone mentioned before, "blank" tiles would be helpful (though not necessary).
Would love to play more, should you ever flesh the game further! :)
edit: I was trying to suss out what this game reminded me of--it's a bit like the logic puzzle akari, except simultaneously simplified and with additional restraints. huh. (and, you know, fundamentally different.)
