Could you try on datingkillmulator.com?
i have tried before and did the same thing. now it won't even open ;-; i tried reseting my mac and changing my wifi but dating killmulator 2 wont budge but the first game can :/
but like when i go to the chapters and click on one it either goes black or its at the last "blinking" animation or whatever :(
btw even the browser doesn’t work and just hates me 😭
here is one of the things it leaves me on after i click it, or just black 
is this it?
