The music and fx were pretty good and definitely captured the gameboy feel well! I noticed some blurring with the graphics; not sure if they were imported like that or if unity aliased the textures. The shooting worked just fine and it was nice that the zombies followed you as you ran. It was a bit hard to play because you didn't have much room to move, and it seemed like the hitbox was actually larger than the character. Otherwise, great job! :)
