This game is so much fun!!! Yes, I say it although I completely replayed the first 6 levels. (Really, thank you...)
We feel that you wanted to create something that produces fustration and it's successful. It's always frustrating to start the game all over again at the end of archanement. However, you should spice up a few story levels or offer bonus levels because once you get the hang of it, it becomes child's play.
That was my opinion. I hope it will be useful to you.
