If you crave violence so much, there are plenty of games that give you exactly that and this simply isn't a game for you. Not everything needs to have "things to shoot" or appeal to you personally. The Drizzlepath games have always been walking simulators and believe it or not, plenty of people actually enjoy these types of games despite there not being anything to shoot or any type of survival aspect.
I hate to say it, but it needs things to shoot.
Some sort of action.
Building and survival gameplay is a good replacement for all shooting.
For keeping cartoon simulated violence to minimally necessary levels.
