Hey! I can confirm on my very old Macbook pro running Mac OS Catalina and using the chrome browser. The game loaded and worked great, although I was bad at killing zombies but it was fun! Awesome work.

ok yeah, I just downloaded it and tried and it did load up! There is the usual mac popup that says you can't open this because its downloaded from an unknown developer, but that happens for everything you download as far as I know. Mac users should be familiar with this but if not, you go to system preferences then security & privacy and then popup should say open anyway mid bottom area of the window. Hope that helps! Probably good to get a test on a newer updated macOS but should work.
