1. Aiming seems a little awkward, you can't really tell when you actually are hitting and when you're not, so sometimes you have to practically dance around a target before hitting them.
2. Kind of dull, (repeating music, just same scream when dying)
I did like the idea as well as the upgrades possible, but this game gets real old real fast without a little more variety and improvement of aim control, other than that fairly enjoyable
The way you have to shoot at the "humans" reminds me of "Space Invaders".
In fact, you could sy that this game is an "Arranged" version of that game. :D
I just realized!
