Oh, i'm a sucker for puzzle games, and this is a very nice one, not much to comment on the gameplay loop itself, i loved it, however i would very much like that a fail/restart would not wipe away all of my signs, wish i could just remove one and try again and that the game would tell me that i could go through signs. Also the camera could follow the knight after the play, but that one is nitpick. All in all this is very solid and very fun, props to you!
