great game
for those who are wondering about the goblin level (13).
i found the way to defeat it on epic mode was to have 4 of the following.
1. sky dragon
2. meteor strike (to kill the black imps quickly)
3. invulnerability.
4. patience.
as far as the game itself, would of been nice to have included a turn off button for the music. an autosave feature would of been nice too... other than that, it's addicting.
