I loved the style of this - it was very evocative, and the almost cardboard-cutout nature of the enemies fit perfectly. It was a clever way to (I'm guessing) overcome your lack of 3D models and make full use of 2D sprites that I thought worked out well.
I appreciated the explanation on the stats - it's always frustrating to me when I have to allocate stats at the start of the game and I'm in the dark as to what they do. I did feel like melee weapons were at a large disadvantage; my first attempt was full melee and I had a much harder time than when I built for ranged weapons.
The enemies sometimes blended in, to the point where I think they might have been facing so their thin side was towards me, but I'm not sure. I also would've liked a bit more feedback on the combat, but a week is a tight timeline and you really cut it close, so it's definitely understandable.
I had fun with this. Good job!
