Good game! I love the art and music
I was very confused about how the real/fake system worked. Im not sure if there was supposed to be some other enemy detector other than the blue bar at the top because just using that was kind of weird because you ended up just waiting for the bar to fill up then clicking it and shooting the leftover zombies. I also think some way to get ammo back would be good (unless that is in the game I could not tell).
Overall nice job for your second game jam game!
