Thanks for the feedback!
Yeah, the balance could use some work. Infected pose little to no threat as they are, and personally I found turrets trivial to deal with too once you find a corner or a crate to hind behind. You can also outrange them since bullets travel for a long distance, but turret vision is limited to 1-2 screens. In the end, I just thought making the game easy would be preferable for the jam format.
