Loving the music, really fits your vibe. Sound effects are great. You've also done a great job on the narrative. Wow, very indepth, expansive game. I love that anything interactable has an animated green triangle. This is such an epic game. I like that the game has "lull" periods, ie. at the end of the day, you get the chance to purchase things, stock up, set up perimeters etc.

I was going to say you might need to drop the sensitivity, then realised this is a setting! Nice work. Would also be great if "Esc" button on keyboard dismissed the menu, and it'd also be handy to have the controls somewhere in the menu if you need to refresh your memory.

It's cool that you get a limited time to buy from a truck at the end of each day. I guess the next thing you could look to implement would be more damage for headshots, and maybe the opportunity to choose  where to place your hired employees (ie. get them to help defend the restaurant or cook meals).

This is such a well polished game, well executed. Nice work.
