This game looks fantastic! The movement flows and the effects are great! The only issue i have is that the zombies sometimes feel like bullet sponges, but other than that, it's a great game!
Thanks for the feedback! Yeah, I do agree the zombies may have a bit too much health. Did you try aiming for their head? Headshots do extra damage, although we may want to add another way to communicate that to players besides a different particle effect.
