Gravity Kills: Newton's Revenge Prototype

This is an FPS where you kill robots and collect their parts to advance.  You need to shoot the correct places on their bodies to get the parts, so aim is key.  You also need to collect new weapons to be able to harvest different parts.  You can spend the parts to open up new parts of the level, and also to upgrade your weapons.  All of this is happening on a space station where you can shift gravity and walk on walls. 

This is a prototype to test out whether the limb collection mechanic is fun, and also to play around with some different gravity mechanics, so please leave any feedback, positive or negative.  Thanks!
