After watching Phil play Love Seat, I decided to get the ending that he never got. This unfortunately has not changed my opinion on the game. But I will start with a positive. I think that the backgrounds look nice, and I like the details of the chairs slowly lowering in numbers.
Unfortunately this is the only positive thing I have to say about this game. Someone else discussed the sound design in a different comment, and I agree with their opinion. Additionally I'm not a sound guy so nothing I say would even be useful.
The character portraits aren't properly proportioned in relation to other characters. Cris looks way too big compared to some of the other characters, especially the bunny man. It feels like they weren't sketched on the same canvas size. Additionally based on your comments, it seems like the art roles were not properly divied up. If I was in charge of this project, I would have one person do the sketches for the stills, another do the ink and another do the flats.
However my biggest gripe is the plot. The structure of the story, and especially the twist, do not hold up to any scrutiny. Characters such as the tripping guy and the south park music guy should have been cut from the final game to save time and to focus on more important characters like Layla, Ralph, Cris and Bunny man. Cutting them from the game would have improved the overall plot, and created less work for the sprite artists. Cris' plan makes no sense. She is clearly stalking and is interested in the player character. Why even bother kidnapping these other people if she just wants the PC? What if the PC fails and dies after Cris "sacrifices" herself? All of her work is quite literally for nothing.
The characters were poorly introduced. All of the players should have been introduced at the start after the PC wakes up. The way that the characters were introduced made them feel like they only came to existence the second they were actually relevant to the plot. It feels like there wasn't any rewriting involved. Someone with fresh eyes would have caught these writing mistakes immediately. I'm sorry I'm being so harsh on the story, but this is a visual novel. The story is front and center in VNs.
Edit: I forgot to mention this earlier but I appreciate your ability to take constructive criticism.
