Alright, finished this, in the end I used LPs and such because I loathed the tiny sprites and shit pacing. Seriously, the game should have been set in 7 or even 5 days instead of 3, as that way things don't feel so compressed during daytime events, only for the final day to go at neck-breaking speed.
Comments and spoilers below.
The game reminds me of Ni No Kuni The Wrath of the White Witch. Excellent production values, subpar gameplay. Not only combat is slow, the dream sections are a deliberate waste of time (in more ways than one). The game justifies it, but it's still boring to play compared to Sunny's daily life. Writing is much better during the day sections too.
Story is good and characters are usually fun. I found it disturbing how shit Aubrey's home situation is, unrelated to the plot ongoing and how you cannot do anything to help her, unlike all other random strangers you (optionally) help along the day just because. Speaking of, while the game has tons of little touches, it also has issues such as save points being placed inconsistently, or easily missable events that you have no way of knowing about unless you had a guide or blindly stumbled upon them.
The dreamworld is also ridiculously big, with tons of areas, secret areas hidden within secret areas, and so on. Shame that as mentioned above, it's not particularly interesting. Worse, all of the side-quests are not worth much, because once you get into Blackspace, your party members and your dream-world gear no longer matter. The Blackspace section is quite cool to explore and disturbing, but then you realize it has no fights, no damage tiles, no puzzles, no bosses, no enemies that can trap you like Yumme Nikki, nada. It's purely for atmosphere.
Then the final day starts, and things move a bit too fast, with Sunny facing his Shadow fears AND remembering the Truth (TM) all at once. Speaking of:
The plot-twist is quite edgy and hard to take seriously. I would be okay if it was an accident, OR Mari hanged herself, but both at once? It seemed over-the-top. IMO it happens that way only so that Sunny can see Mari's open eye, realizing she was still alive and he killed her, just to set up a black comedy moment taken from LISA.
Basil has some "interesting" ways to help people, or he's from a mob family. There's ingame text about the truth section but it only makes the whole thing look edgier. Perhaps that's why the photos are left to interpretation.
Next, Basil and Sunny go nuts as the former undergoes a psycho breakdown, culminating into a stabbing contest, all while your friends are sleeping next door, heh.
Finally, Sunny faces his final foe, which following Mother games' tradition, it's an unusual final boss encounter with appropriate cool music. Then the Final Duet happens and you'll probably bawl your eyes out.
The good ending is bittersweet, but it felt fine... There are more endings though, every one worse than the previous ones.
Meanwhile, the alternate route seems like an afterthought, with some cool scenes and situations, but not worth trudging through 30 hours of gameplay again. The BlackSpace 2 section though makes you wonder about Omocat's sanity, for good and bad.
Some details I liked is how Shinji Sunny starts his "serious" fights afraid, until he gathers his courage and starts the final ones in a neutral emotional state. Moreover, Sunny seems to like running away from his problems, seeing how you cannot help Basil the first time he's in trouble, how the game flips the punctuation signs during important battles to empathize the "RUN!" button and so on.
It's a shame there's no final dungeon right before the endboss, if only so that whatever time you spent to get your party members' endgear wasn't a waste.
True, the point is that the dreamworld is an intentional waste of time, but I think the game sabotages itself by making it too much of a good point. That wouldn't be an issue had the game been set in a more reasonable timeframe, allowing smoother transitions. Another missed opportunity that ties into this is that Sunny doesn't suffer from agoraphobia or anything. Instead, he can run around and talk to people normally the moment you answer to Kel, despite having been a shut-in for years. But then again that comes back to the 3 days time-limit, which required drastic action in order to cram the content in such short time.
Long story short, it's okay. It could have been better with some polishing touches, and I bet there was some MASSIVE mismanagement in the dev team to take so long to produce (ie: the "final duet" thing wasn't finished right before the game was released, and I believe I read somewhere Omocat wasn't sure how to end the story). It's not as good as LISA or the OG Mother titles, but it certainly has better writing than Undertale. For one, while "they" is unfortunately used as a neutral pronoun, boys and girls are referred by the right pronouns, as it should be. The MC is also hetero for sure, despite what the game trailers can make you believe.
In a whim, I snooped around to read about Omocat's personal life. Reading between lines, her life is much more depressing than this game's story. That explains why most ingame parents are always faulty to some degree. Also, the dev is a NO FUN ALLOWED ass and you cannot rename the MC using rude words or stuff like that, despite this being a single player game.
Now, the only Earthbound clone remaining to play is the Jimmy one, but that will be for later, once I'm not fed up with JRPG gameplay.
