Interesting; unfortunately, the QWERTY-based controls makes it rather difficult for me and my AZERTY keyboard. Once again, as I already told quite many people: it is possible to program the keys to be layout-independent. Think of your French (and other) friends. ;)
I also notice (thanks to my messy controls XD) the W key allows you to zoom, but this is not stated on the game page; you should specify this. Except if it is involuntary default control. ;)
I like the details, especially the integrated 3D visual indicator (circles) for the number of cartridges in the shotgun.
The game seems a bit hard, but this may be caused by my messy controls… I will give it another try.
The left button of the mouse is mapped to the right-hand weapon, and the right button is mapped to the left-hand weapon; this sounds terribly counter-intuitive to me, I would suggest swopping the controls!
I think the concept is somewhat creative, because the randomness interpretation is classic, but constantly switching is a bit different/original; the gameplay also still looks workable, which was not obvious before playing.
