Really cool fps shooter, it was really fun :) I didn't really like the blood splatter particles, they were looking weird. I also found a few bugs. I opened my inventory and press ESC to close it but the cursor stayed on the screen and I had to click/shoot to make the cursor disappear, just a small bug. And also after finding the fuse I heard zombie noises behind me all the time but there wasn't anything behind me, a really weird bug. Also, the gun and hands are not affected by lighting and I know that is because they are not rendered on the main camera because they have a separate layer but I think it just looks weird.
Overall really nice game, I enjoyed playing this and I love fps survival horror games :) Keep up the great work can't wait for the continuation / full game
