This is definitely one of my favourite games so far. I love the infinite generation; I expected it to drop some frames in the web version at least, but it ran super smoothly for the whole time. The game feels really polished; the post processing on the camera is tasteful, the gun feels nice and effective to shoot, and the enemies don't feel too hard. It gets increasingly hard as you start to run out of ammo and need to go and find more, which is where the world generation is a huge help. To improve, some extra world features or biomes would do well, and some more weapon types if possible. A 3D gun model would be nice as well. Really good job!
