Awesome game, I didn't feel feel bored for a second. I really liked the progression with the gun types, each of them presents a unique mechanism, instead of just shooting faster or more bullets. The sound effects are simple but give it a nice comic vibe.  

The specimen will keep circling around and you just have to wait until they loop back inside your shooting range. At first it seems like a flaw, but it makes the game more challenging.
