Hey Captain,
you are building something outstanding here.
I love:
1. Your focus on the small cast of characters, so we get to know them really well
2. The high number and impact of player choices
3. That there are two relationship routes for each character that even blend over
4. The strong emotional and complex relationships between all characters (also between the girls)
5. The overall high quality (writing, visual, spelling...)
If the remaining days turn out as great as the first 4 ones, the final game will be better than Acting Lessons, Being a DIK, Depraved Awakening, Dracu-Riot! ... and every other visual novel that I've ever played.
There are 2 things I would like to see in the future:
1. More Humor: It's hard to come up with good jokes, when you don't have a natural talent for it, but I would love to see some funny scenes with the girls.
2. More details about the characters: I would like to get to know them better. What do they love and hate? What kind of music to they like? What do the girls like except hanging out at the pool, running, taking a shower, watching movies and going to the mall? Of course not as bland exposition, but weaved into scenes or maybe into the environment? All the environments are pretty clean and impersonal right now. There could be posters, pictures, books/CDs lying around... that give cues about their preferences and background.
Do you have previous experiences as a writer? You definitely know how to craft dramatic scenes and fraught relationships.
Keep up the amazing work. :)
