Fun game loop. I think hitting perfect shots and having more arrows is more important than shooting quicker, so I always went with faster arrow production speed. I like the shooting, you need to know how to lead your shots when the zombies are moving. The visuals/sfx are very cozy, and seeing the zombies come from the fog looks cool. I think it sticks close to the theme other than the "build" part; which could just be you "building up" your stats with the daily powerups.
