Hello, I played this game and I really enjoyed it, loved the environment and art style, good work :)
Thank you so much for playing, I'm glad you enjoyed it and your video was actually really useful because I spotted a couple of bugs:
- "Walking" should be deactivated when player is swimming (I think this is why you were swimming slowly)
- Crawling shouldn't wake the zombies up
Also, I guess I should say that you were "lucky" in your playthrough, there's only a small chance for the red light to show in the demo :)
