I love the flashlight aesthetic in this, it really sets the mood of the game. I ended up getting around 50,000 before I stopped. At the end I was just spinning in a circle clicking all around me and no zombies could get to me. Nice job!
Some things I was thinking would be cool while I was playing: having furniture or something be obstacles so you could make the zombies (or yourself) get caught behind them. The zombies and character also moved pretty slow for me, so idk if that's a webgl thing or what. Also, I think having a "stamina" or something for the flashlight so you can't swing it while it's off would be a good mechanic.
Thanks for sharing, I enjoyed it!
