Great Tower Defense game, looks need, offers good strategic options and limitations.
Without the Ninja's the game would be too easy.
To win from champion Ninja's just have meteor mana cost and damage upgrades of the demon tier to the max and shift+meteor 5 times for the win.
Finished at level 36, could be sooner if I didn't neglect Demon tier.
Best tower to begin with are crypts imho!
Not funny, was searching for the boss for ages, never found it.. Was gonna add a bad reply for the random badge but then I saw that I've already beaten the boss xD
Funny small game, good for 15 minutes of joy :)
