ok first off this is one HARD CORE game and takes skill....but skill or not it's really fun! the sound is the best thing for sure keeps you playing just to hear what he says that is entertainment and i think that many people making games overlook the sound far more then they should good on ya for that.....i gave the 6 for graphics because it was only shadows clean yes but not much to them, add some stars or a moon and maby buildings in the background and maby a tree and some grass blowing ....of coarse you can still do this in shadow but it would add a little without takeing away the feel of the game also it did lack a bit in upgades still they wer good too anyway i love this game over all and i hope you make new games with this kind of style it's very uniqe :)
