Katawa Shoujo (and it's a free VN on top of being great)
If you want a laugh, you can try My Girlfriend is the President
Planetarian: Reverie of a little planet is a pretty sad story, won't spoiler it more than that
World End Economica, divided into several episodes
Brilliant Shadows and it's successor, Pale Spectrums are two I kickstarted and found them very interesting and love the art style
A bit more special is the Invisible Apartment series, but I liked them (and kickstarted it too)

Btw, how did you like the Letter? I kickstarted that one too like some others on my list, but didn't have time to play much lately, still with the first character
