A compelling story presented with good writing, good art even where it's just sketches, and catchy music.
It's also realistic, with perfectly nice girls I'm not interested in practically throwing themselves at me, while the one I'm really interested in tries very hard to be unobtainable, *sigh".
This game is already worth playing in its unfinished state, and could be really good once it's finished.
Anyway, I wanted to suggest selling the game here for "name your own price", as I'm sure some people would be willing to donate to you that way, since it's less friction than having to make an account with yet another external service.
