Hi thanks for the Continued feedback!
The Next version has been slightly delayed to incorporate the feedback you have provided. I have a build ready and meant to upload it over the weekend but I have also entered the Epic Game Jam so rushing to finish that (you only get 7 days to make a game from scratch) has delayed the new version. I will address the issues you have raised particularly the zombie amount and the first person limbs.
Expect an update within the the next few days!
