I got the first ending. I noticed there were numerous typos where the apostrophe was forgotten when spelling somebody's name in the possessive.
Otherwise, I had to put down this visual novel at first because it bored me a lot in the beginning. I could see the conflict and the potential, but the beginning threw a lot at me at once.
For starters, it started with dialogue, the dialogue was heavy-handed and left nothing to the imagination, there were no questions or mysteries for the reader to have, there were five different characters to keep track of, and three out of the five girls were blondes. Not only that, but they all dressed in similar outfits. So, it took a bit of time to get everyone in order in my mind, but they all had their own distinctive personalities, too, which helped.
I think if the story eased into the world and the main heroine more, it would have made for a better introduction, as I didn't get much of a sense of the main protagonist of the story from the get-go. Furthermore, I had no reason to care for the main character, her want for the revenge, or the other characters involved.
I thought the other characters were far more interesting and seemed more fleshed-out compared to Diana, who I felt like was a bit too much of a blank slate of a character. Additionally, I didn't care about Denise, who I know nothing about, which I understand that's the point. However, it's hard for me to care about the past if I don't care about the present.
Regardless, the story grew onto me over time, and the voice acting was great. Sometimes, the voices were too quiet at times. I don't know if that was intentional or not.
Otherwise, I liked the art. The backgrounds were fine enough for me. I felt like thee text box got in the way of seeing the character sprites, but that's just me. I give it a solid 7-7.5 out of 10 so far. I would have to read the rest to see where the story takes me.
My only other issue is that the gallery shows a big CG without a button to go out of that mode or a button to see locked or unlocked CGs. If the gallery section had a display of the different CGs on screen in rows and columns, that would make it a more manageable experience to navigate that page. Just a suggestion there, though. I also think having a load and gallery button would go a long way in the main menu as well instead of having to start the game every time to access those features. Again, just a suggestion there.
Good job!
