This is a really unique take on the theme. I like the pixel art numbers. It's especially creative that the vampires you have to shoot are numbers, and you shoot them in descending order.
Do the counts randomly spawn or do they have a set spawnpoint? I panned right every time and then doubled back and they spawned/were there almost immediately after doubling back.
Nice shader work and great parallax. I do wish the shoot button was available immediately instead of having to load. Though I suppose that's to make the game a little harder. So you can't go "OH THERE HE IS- BANG."
I shot one citizen cuz I couldn't find the count so I didn't know if they could disguise themselves. Despite that I got S+.
Great game!
