I actually like the way these controls work. It lets you do full 360 degree aiming with only arrow keys. Even though it's a cool concept it wasn't very fun to use. The difficulty curve is also a bit steep, and I kept dying on the level where you can see which enemies you need to kill. If I could restart from the beginning of that level rather than the very beginning, and if the friendly snakes didn't shoot, I would have spent a bit more time trying to win. Besides that, though, I really like the graphic style and ambient soundtrack!
