The idea behind this game was also one we were thinking of. I like the gameplay, each enemy has a well thought-out unique attack. Took me a round to find out that I could move, maybe the 0 reminded me of a stationary object. At first, I was just shooting everything, also the ones, even though they were green. I guess my bad for clicking too fast through the story/instructions. I liked the ending of the story that ties in with the theme. Only "negative" for me was the bullets +1 upgrade, which meant I could not click anymore on the objects that I wanted to shoot, as both bullets would miss the target (one on the left, one on the right of the target).
