I like the gameconcept, I only don't get the flying castle part, so you can actually fly with it??
No, it's looks something like this and is used only to advance to the next level.

When you conquer all the enemies in the area and collect enough magic crystals, you just press the button and fly to the next level.
I was like how big was it going to be?
That's the point.

Player should be all excited to see how the castle is gonna look on the next level.
Maybe some time later I will do 20 more levels. It's not that hard. (Except for coloring)
Thank you guys for all the comments! Ill do a colored sample in a few hours.
