Wow, I'm glad someone noticed the pitch shift. :D I love low poly 3d, so I'm glad I played your game. I think you can acttualy use a similar pitch randomization method when the characters speak. It's an easy way to make sounds sound less repetitive. Outside of that, I would add some screenshake or more particle effects when shooting, but I'm guessing that couldn't be done due to the one week limit. Awesome job and I'm glad you liked my game too!
