Hey, looking very good, I think. Good job on the coding especially. I like it.
I think it's really hard to aim. Maybe I didn't know about some function you can use, but I can't aim with those guns...
also, I had problems when i walked too close to the walls inside the house. third and last when I chose some weapons that I had chosen before, their position was weird so that you could only see a small part of them on screen. But, all in all, I think you're doing great!! keep it up!!! and keep on posting nice little demos
