I agree with blizard, this game really needs a higher rating, and more plays too, the rating is probably due to all the people who are like "oh theres a gun but there isnt enough shooting 1/5" when its not like that at all, the game really interested me, and even though i dont have the patience to sit here and figure out what the ending meant to me personally (XD), i still throughly enjoyed it, and i liked the few sly tricks to try and make you go backwards :P
Oh i also figured out you can get two shots in on his head at a time if your good at timing your jumps, because if you shoot him as soon as the top platform appears, as it disappears, you can jump and shoot again :P
Definatly deserves my 5/5.
