Yes thank you, I did manage to complete all the levels. Level 9 was much harder than level 10 though, because of the timing of the first dragon. I also found that you can't walk over the dirt wall next to the exit door (level 9) and it did seem like there was a really small deviation in timing between the creaters whenever you restart. In addition to the knight sometimes getting stuck for a few second when hitting the large dirt block in level 7 (when changing direction before going to the platform with the snake at the beginning).
