Really fun. At first I was really struggling, but got the hang of it after a while. Once you get a good rhythm going its not so bad. Really liked the section with the alternating cracked tiles and you had to keep jumping diagnally across them. I also appreciate it continues from where you fell off rather than starting you at the beginning.
I had 2 stars left and then I accidentally clicked my bookmarks bar at the top and it quit out. I'll give it another go soon, its tricky but really fun!
