I am not seeing what leveling up does unless all it does is increase health a minuscule amount. Also I think the areas with a literal 0 risk shouldn't be subject to the same risk of being caught from noise by zombies that aren't there. It doesn't make any sense if you do. There are other little things like how everything breaks way too quick for the resources reproduction rates and the rate which you're caught because of noise. There are also some locations I think it was the store but it was one spot there that I went there 3 days in a row and every time I searched it I would be caught and then I just gave up on it. Otherwise good game bet the end product if made right will end up something like Summertime Saga or the others.
You need to remove the name of the game you just mentioned because if a moderator sees it, they will delete your post (it's advertising).
For the lvlup, indeed, you only gain 1hp per lvl because if you get other stats on top of that, you will quickly be invulnerable. To do this, you will have to find the riot gear.
For the durability of the equipment, I found a small bug that makes you lose 2 points per hit you receive, I fixed it but as I didn't note it in my notes, I don't know in which version this is fixed but Kate's workshop can be improved up to lvl7 so you can have weapons, Tier 2 jacket and pants (more powerful and more durable). Also, I set the code so that each hit received only hits one piece of defense equipment so the more piece of equipment you have, the more likely it is to keep it longer.
For the DANGER system, it simulates the movement of zombies on the game map, this does not include the inside of buildings because they always manage to find a way to get in and end up locked inside. BUT just because an area looks harmless doesn't mean there isn't a zombie lurking (this often happens in horror movies or series).
For the harvesting system, I took a bit of inspiration from another game in which if you speed up the search, you might make noise and attract zombieS. In this game, the noise will always attract only 1 zombie (I specify because the arrival of area 2 and 3 will add the probability of fighting 2 or 3 zombies in addition to the fact that they are stronger). As for the return speed, I find this one too fast (if I go back to the other game, the resources never come back).
PS: It's not just in the store that there are search points. They are in every building.
When a zombie is going to run after you, there's always an indicator above its front head so you have time to run and move faster (if you have the run function enabled all the time or if you press the run button. If you play with the mouse, the character runs around all the time without activating anything).
When the zombie stops following you, it returns to its starting place. He doesn't see what's going on behind his back.
