I'm at the part of the story with Altina being bought by the MC but so far, I very much agree with one of the comments down below.
The protagonist is a wuss. It doesn't feel like I'm playing "as" him but rather, I'm just watching him be dick on himself. Last I checked, the description says that the protagonist is supposed to be the "hero of the story but he doesn't feel like a hero at all. He saved his landlady and friend, then revived Azula but after that, everything went downhill regarding his character. He's too indecisive in scenarios that matter the most. On the off chance that he makes a decision, the story forces you to make the worse choice. For example, the story established Vie as an extremely arrogant and hostile character towards the MC but doing Altina's questline, you're given the option to tie loose ends with her or let her go. Oh. Lo and behold, you get a game over when choosing one of the choices.
Second, some of the romanceable characters aren't likeable at all. For example, I get that Estelle is a tsundere type but the way she's made is, well, annoying, to say the least. Her lines are so overused, she doesn't improve her character, she gets involved in other characters' story arcs so much that it's more of a hindrance than a joy to see it. By the time I get to her own story arc, I already got tired of seeing her that I no longer paid attention to the dialogue and just skipped everything because I already had my fill of Estelle screen time through the other quests. Same with Azula. Her character is extremely ironic by saying that her species don't care about morality but she chastises the MC for lewding on other girls, specifically Altina's questline.
Third is the lore. It's so jam packed with story that it's getting old. Don't misunderstand. I like it when novels delve into the details but it's done so rough in this specific title. Flashbacks, for the most part, are welcome, but it is so out of place in here. As an example, a good flashback chapter is done in another visual novel called My Bully is My Lover (if any of you reading my comment read that novel, you probably know which chapter I'm talking about). The flashback in that visual novel chapter is EXTREMELY LONG but I did not feel tired of seeing it. In fact, I would've replayed the novel without skipping anything. However, in here, the flashbacks just makes the story more vague contrary to MBiML tying up loose ends in the story via the flashback. It is not enjoyable to say the least. Besides, I feel like the flashbacks are trying hard to give personality to the characters involved but it's doing more harm than good, IMO, because one, I'd rather give the screentime to the MC and have him improve his personality instead of establishing something else that happened outside of the novel's time setting. Two, you're walking on the edge of a knife here by showcasing the girls involved with other dudes. I know they aren't NTR, just to make that clear but I wouldn't want to read a story about a guy watching his girlfriend's old AV tapes.
Fourth, side characters. They are getting introduced by the droves and it's becoming a chore to remember them. I don't know if you have a plan to involve the Champions into the romance but they don't interest me at the moment. Suddenly focusing the camera on them when the questline is about someone else is annoying. I would've understood if it was a Main Quest but nope, it's listed as Altina's (Honestly, it feels more of a main quest so just gonna put that opinion out there). It's the same with Estelle as I mentioned above. She's way too involved in other character's story quests.
Now, I may be blabbering about Altina too much but that's just because it's where I noticed a ton of really bad story details. It's not an isolated case. I can pretty much keep going with Estelle, Celestia, and Laureate.
With the Princess, she's the same as Azula. Her character is extremely ironic. She's the person running the Scarlet Contract business but she chastises the MC for using her services.
Makoto's mistaken for a guy trope got old after the first one.
Celestia's character development is downhill. She was a better character before joining the household. At least, she was doing her best when she was living in the street. After being bought, she turned to this kind of slobbering mess of a person. The story isn't helping by justifying it as "half breeds do what half breeds want". Contradictory, I'd say. She's tamed and educated judging by her story but her current personality says otherwise.
PS: I'm not doing this criticism out of spite but rather, in hopes of seeing improvement to the game.
Cheers!
