Great-looking and sounding game. I feel like player movement is too slow, it takes ages to get from one rune to the next. Also, I felt that the game could need some more challenge (maybe some more platforming etc.). Otherwise a great entry.
I agree with the player movement, it feels very slow. I thought about making it faster but i think that would have trivialized most of the challenges but i think i could have come up with a way to make it work :)
