Fun game with a cool art style, my only criticism is that it seems a bit too RNG based, in that you could get the "right" rune 4 times in a row and then have the next 20 runes be wrong, meaning you could have to only get 5 in a row to win, or you could have to get 20 in a row. (Possibly some cap on how many "wrong" runes you can get at a time would help)
Other than that, cool concept and a good ending
