This game is definitely filled with pros and cons. While I did think it was an improvement from the first two games, there's definitely some issues to be taken with it.
This game has a simulation aspect blended into the visual novel experience. Each day, Heileen has to choose certain activities to do in order to increase stats for skills and advance skills. While I definitely don't have a problem with simulation aspects being put into visual novels, I must say this game's sim system is quite tedious. It took me several hours and several playthroughs just to get all of the achievements, because the simulation portion of the game takes far too long. Those who don't have a lot of patience would definitely dismiss the game quickly. Meanwhile, I almost developed carpal tunnel syndrome from clicking so rapidly and frequently. The basic concept for the activities and stat development isn't terrible though. That idea is fun, but I definitely wish they hadn't made it so tedious.
A lot of characters from the previous two games were brought back, with one new character being added as well. This third installment definitely tied up what happens to everyone. All together, there are four men and four women to choose from for romance options. While I'm glad they weren't heteronormative, I must say the choices aren't really that great. John, Jonathan, and Sebastian are all terrible people in their own way. Morgan's the best out of the whole bunch, but even he has some issues. Among the women, the best is probably Ebele, considering Lora's incredibly vain, Marie is annoying, and Juliet has some serious anger issues. This isn't to say that romantic interests shouldn't have flaws, but my biggest gripe is that very few of the choices are particularly appealing or even good people for that matter. Once you get past how some of these people are awful as human beings, the romance scenes were decently written at least.
My favorite part of this game (and the second game) is the virtues and sins theme. When making choices, a lot of the time people don't really think about how it could affect others or themselves. When people refuse to donate to a charity, they probably don't think "that was a greedy choice." When people remark on how they don't feel like doing something, they probably don't think "I'm being a bit of a sloth." Unfortunately, sometimes the choices are rather obvious about which virtue/sin it reflects. Some are not so obvious though.
On a technical level, the game seemed fine. I don't recall running into any errors or glitches. I don't think I saw many typos either; I think there might've been a couple though.
There was a bit of a pet-peeve I'd like to point out. There were two particular scenes that really bothered me in this game. Both involved Heileen being sexually harassed, and when choosing to defend herself, both actions were seen as "wrathful." Um, no, self-defense against men who literally refuse to take their hands off a woman's body when told to is not wrathful. Wrath is having uncalled-for anger. Self-defense isn't an uncalled-for action whatsoever.
Do I recommend this game? Yes and no. It can be fun and interesting. If you like visual novels and don't mind the tedious repetition of the simulation aspect of the game, then sure. It isn't half-bad for a visual novel. If you're not into any of that, then definitely don't play it. You'll hate it.
