I liked the way you interpreted the theme, and the concept you came up with thereafter. There were however multiple things that I disliked. To begin with, the music was a bit annoying. Next, the controls, specifically shooting, felt very unresponsive and didn't fire every time I pressed a button. Neither did the shots go where I aimed with the mouse, but rather a few degrees above.
The tutorial in the beginning was good, but the time between each text was far too long. I felt it should have been 0 seconds.
For the visuals, it looked good. The worshippers themselves looked quite squished though.
