Ehh. If I didn't love dragons, it wouldn't have been worth my time.
The big actual flaw in the game is that damage to enemies tracks where the mouse is, not where the visible flame is. It's most noticeable when trying to destroy the jets, but it's also seen when helicopters fly through massive amounts of flame, to no effect, but explode when ahead of the flame stream.
Short, iffy, and nothing new. But only the one apparent programming flaw.
