It's looking very promising!
I did two runs, one with each girl. On my first run I missed the first weapon shop so I played only with the silenced pistol and the flamethrower you find mid-way through the level, I used all my ammo in that run so once I got to that button that opens the last door I started over with the other girl (the brunette). In this run I did find the shop and it was much different, I got to the end and got to try the minigun as well.
I don't really have much feedback since it is a work in progress, I did miss a melee option since I used all my ammo on my first run. The blood splatter looks awesome and the designs overall look pretty cool.
Great job osur! Let me know if you need help with more testing or something else.
