Melody is a beautiful game in many ways, but is ultimately unsatisfying for two main reasons.
One is the storyline/pacing, where the root of the problem lies in both the MC and Melody being so frustratingly hesitant in their actions, with every single action being a crisis of conscience. Both are whiney and not very interesting characters. Story development then suffers as nothing really happens, except the MC gets to inch a little further into Melody's shirt each time. This sort of storytelling has made "sex with Melody" the final ultimate goal, whereas a better VN would make "sex with Melody" a significant but not final step in the larger story of MC and Melody's relationship .
For example, I like Aunt Amy more than Melody partly from graphics standpoint, but she's also a more interesting character because there's a lot more left to her story even after the MC's had sex with her. That's...way more interesting.
Second, the art/graphics. The backgrounds are lush, but the actual characters are problematic. Reusing renders from other games could be fine if the are good/updated, but all of the female teens still look like they're deep in drugged thought. The posing is always awkward, with the arms almost always at unnatural angles and poses. (Seriously, how often do people pose with their arms akimbo?) I think Amy's the best overall character, but even still her arm posing and wide-eyed/mouthed face can be off-putting.
I know I've come across as negative; there are a lot of good things for game. The themes are good, the game is beautiful (other than the posing), and the points system is useful. I will still play it, but I'm disappointed when I think the pacing and graphics hold it back from being a truly good game.
