Game's amazing, the story carries it hard. Everything else is somewhat rough around the edges:
There are often noticable mistakes in the dialogue, I'd recommend you to get a second pair of eyes to look it over. Decisions are rare but feel very impactful. Humor is a bit rare, but when it is there it usually hits. Visually, the game is okay. The character models look good but proper lighting is often close to nonexistent. Animations range from bad to good, lewd scenes are alright. They often don't have much buildup and also not much sensuality. Music is good, tracks get reused often but that doesn't have to be a problem. The audio in general is sometimes not mixed well, meaning that I found myself turning the volume up and down manually a few times.
In conclusion: amazing story, but mediocre quality. Though I don't really mind, if you'd put more effort into the quality, episodes would prbly take longer to make :P I very much recommend this to anyone who likes a good, story-driven AVN!
