Thank you so much for all the kind words, it really motivates me to keep working hard on the game :)
In the few scenes where you catch a glimpse of the MC, he's a very normal looking guy with black hair. In games like this, I like to leave it as 'self-insert' as possible, which is why he doesn't have a defined look.
Maybe in the future if more people want to have a concrete MC character design, I will make one, but for now you can just think of yourself or whatever you like :)
Personally I agree with you and prefer that he stay less defined, appearance-wise. Even when small aspects of customization are added, it's usually not enough to feel like 'me' due to the amount of work it would take and thus we end up seeing them everywhere with something only vaguely resembling our own preferences, which is annoying. I prefer that the MC remain exactly as 'anonymous' and hardly ever shown on screen as they already are, for maximum self-insert immersion. And in that vein even if you were to give us fully customisable MC, all that would do is take away from the time you have to give us more of this amazing game. It's one of those things where I think either have fully integrated customization which is great, or not at all and keep MCs appearance as 'up to your imagination', as possible. Which in the case of a still developing game is I'd say the best way to go about it, at least for the time being. Like the only time I really want to see his face is in special moments like if he's being kissed, or using his mouth for something. And you've already done an amazing job of making him feel more like 'us' than a separate character.
