Ah, I didn't realize this was released during Quake Expo ... maybe because I didn't remember the name of the project.
I just loaded it up. Very nice ideas there.
I had been waiting for this for months just so I could use a key as a weapon!
It took me a minute to realize I needed to hold down shift to move the mouse pointer.
For anyone else reading who hasn't seen this:
1. You hold down shift to move the mouse.
2. You see your inventory by pressing TAB
3. You can drag-drop an inventory item like a key and use it as a weapon.
It says release alpha 0.1 so I can't wait to see more of this.
