3/5. The effects were really cool, and I thought this was a cool concept. The gameplay itself, however (having to find the right square, kind of put me off.
4/5. Great concept, and a very unique spin on tower defense. I think, like many others, there should be more upgrades, and possibly a way to adjust the difficulty. Other than that, awesome.
This game, to me, seemed to have buddhist overtones. if you follow the voice, you gain clarity and understanding (left hand path), but your world is empty. If you disobey, you gain vibrance and spread color (sort of right hand path). However, if you take the middle hand path (of which buddhism is claimed a part of) you have both. I'm not buddhist, and the gamemaker probably didn't think about that, but it's interesting
