Fantastic concept, can't wait for the next updates, may I suggest having some form of upgrades to your towers, perhaps based upon how many kills they get?
Not sure how everybody sees it completly as a drug addiction, it seems so much more like a self harm symbolism, maybe it's just as everybody else has put it - you see it in your own eyes, that's why some people see nothing in this and others see drugs, break ups, reliance on people and blading
nice game 4/5, and for those people going on about defend your honor, the characters from tht are based on these characters, there almost exactly the same -.- morons...
