LOVED the artwork, but either I had a bug or that there is no goal to get to? (at the end I just strolled outside of the screen, and couldn't find anything relevant to do).
At the end of the day, I think that "my weapons act out on their own" is a really cool thing to base a game on, but you could go further than that to make it shine, because I almost didn't care what weapon will shoot now as long as some kind of firepower was active. Give me more challenges that relates to the pro's and con's of each weapons, preferably both, so that it will have a greater effect on the experience (:
