I have two things to say: Dynamic lighting is awesome.
Turret shootingsounds hurt my ears so bad i allmost do not care if my character dies. Imo that's a good thing. Makes me feel more engages. I'm like: hum di dum di dum. *Light* ZZIZZZZIZIZZI AAAAAH MY EARS!!!! GTFO.
Get boring quickly. Very entertaining while it lasts though. Usually get it perfect on the second or first try. Maybe it's too easy.. GREAT music imo. Allthough it's repetetive. (loop) but i want it.
