I wanted to play this game again, but I forgot the name of it. Thanks Kongregate, to make this game a badge of the day. Now I can finally complete it :)
I have no idea how to get Brilliant on Level 14. I can use the meteor spell 5 times, that deals ~2000 damage. But the ninja has 2500 HP, and is invisible until he reachs my gems.
