Great Game to be honest. This is my opinion and maybe just me. Well I don't really like the title because y'know, if someone that known japanese culture read the title then they can imagine what will gonna happen. It's not wrong but somehow it doesn't feel right for me. Maybe if you named it differently like only "Ako" or something else on one gonna believe it as Yandere game.
p.s. so really much effort at weekends appreciate your work buddy. That give me so much motivation to start my WIP projects again LoL. Thanks
