We really like the concept but the execution felt lacking in a few areas. Some extra polishing time could go a long way and giving the player more feedback would help! (i.e. Zombies reacting to being shot and/or not just disappearing when dying) That's obviously not always possible with a Game Jam so its pretty forgivable! Some bug cleanup and some other polish would improve this a lot! You seem very capable though and we think with more time this could be really cool! :)
