Congratulations to the artist, I'll absolutely donate something to support and stimulate the creation of many more amazing arts!
This game is awesome! I found a bug tho: on the rolling rock level, i fell on the rock hole (while going from right to left), but didn't die and the game just stood there and I couldn't do a thing, other than reseting it.
