Looks super good
The characters are really well crafted (probably in the eponymous Blender of 'Blender Knight')
They all hit me in the nostalgia, but I can also appreciate them from a modern standpoint, but as someone who grew up with alt girls, nerd girls and cheerleaders as fetish fodder I definitely feel like I am the target audience.
It definitely also feels like he is flexing a bit with most choices having at least some impact on dialogue if not more, though if he can keep that up, then extreme kudos.
I personally like shy/careful protagonists, but it can definitely be a bit much at times, though it makes sense that he starts off this way, being basically a fit basement dweller.
All in all I can see it go very far, even if the quality and care stays at half of this level.
Good job Blendie!
