I created an account just for this studio alone, I have now played one and a half of their games (Half comes from... DachaBo, don't blame me!) And they both are amazing. Just, "Extended demo" is just that. A demo? This game will grow, yes? I see potential and this studio is one I will keep an eye out for. I may not have much to go off of but this may be the best studio on ich.io, or at the minimum the best visual novel one. So my best words go out to you, devs, here's hoping they don't fall on deaf ears (No insult intended)
P.S: To ask in human terms, this is not the whole game, right? There will be more? Here's hoping
