Kill Zombies Idle

good game but small concerns.

I like the game its very simple, aesthetically pleasing, and addicting. I noticed even when buying the auto option for the zombies in the research pods sometimes I have to reset the research myself for the first zombie. I had to do it twice for the third zombie. I think its kinda weird. We should also be able to register an account using google or something so we don’t lose progress if we lose a device/switch to another device/have to redownload to fix an issue. Most of the humans barely shoot because the humans with the farthest range defeats everything quickly. I am only on level 51 right now maybe this will change later on, but I would like to see them all attack and not just stand there for the most part. I still have not had the black screen issue which happened to the others when they bought/increased the level of the last human? So, for now I won’t use the last human.

Literally unplayable

I played for several hours, until at one point, every time i tried to upgrade anything it would take me to the gem screen and tell me to buy more money, even if I had more than enough to buy the upgrade
