Just tried out Lust Brave for the first time. It doesn't seem to have a thread of it's own, so I'll just post my thoughts here.
First up, I know that it's cancelled, so all of my 'suggestions' below are hypotheticals rather than something I'm actually hoping for in a nonexistent future update.
Still it was an interesting twist with new ideas, so I like it.
IIRC, the reason for the cancellation was the art taking too much work?
Personally, I like the art for the main characters, it feels much stronger than lust-doll's chararacter-model. The backgrounds and such add a lot of detail too.
Frankly, LD was always kinda... abstract? You get a bunch of blocks in screen and you have to interpret that this is a tree and this is a stone pillar and so on.
That's still here, of course, but it feels a lot clearer.
The general plot of exploring an island feels simpler and more contains than lust-doll's random roaming, which is nice.
I also very much enjoy the dynamic you get when you have two characters interacting with each-other.
LD has characters and sometimes they even follow you around in battle, but they never really feel like party-members.
Also, having someone be around to witness the things the co-protagonist is going through is always amusing.
On the other hand, from the very first section of the game, it kinda felt like NTR bait.
That sort of thing doesn't bother me as much as some, and I might be barking up the wrong tree, but I've played some really awful NTR games that stick in the memory and now when I see certain things in games it just sends up red flags.
Main girl is the fighter, the boy is support/healing. That's fine, it's an interesting dynamic, and it's always good to give partymembers preset roles to grow into. Makes combat feel more engaging.
The guy not being able to deal any real damage, regen his own AP like she can, or take any action to free the girl when she's captured is a bit of a red flag though. It means that he spends a lot of time standing around helplessly, which is kind of a staple of the NTR genre.
Him getting turned into a plushy is...
Honestly, I'm not sure what practical or narrative purpose that transformation was supposed to fufil.
I was half expecting him to get turned into a girl or futa (since the kink-warning page popped up right before that) but him getting squished just seems to lock him further into the support role, which would be fine, except it also removes a bunch of his support skills, including HP and AP regen, which make him much less useful overall.
Edit: Actually that loss of skills seems to be from him losing his scarf thing, which for some reason he can no-longer equip after shrinking?
Not sure if that's actually intentional or not.
The mushroom section is interesting. I was expecting generic lust spores, not some sort of freaky hallucinogen that also lets her communicate with mushrooms.
The dialogue with them was pretty good too, though I never did find the jacket that got hinted at.
It did kinda bug me that there doesn't seem to be a reaction to losing to the mushroom boss. Even if she makes Alisa cum till she passes out, alisa doesn't really comment on it.
Or maybe that was just because I mopped up with Jin and actually ended up winning?
I know if you lose to regular damage before getting captured you just get the normal 'leaving the mushroom area, spores wearing off' message, except Alisa has her clothes on even though the dialogue says she doesn't.
Anyway, my thoughts on this is that Basil should have kept his human form and maybe gotten in on some of the lewd action. Either with Alisa herself or him being molested by monster-girls as much as she was.
I mean, monster-girls are equal opportunity sexual harassers, right?
If you didn't want to draw/write about a guy, then turning him into a futa (either in gameplay or retroactively) would allow him to serve basically the same role.
As for things I didn't like...
Water nymphs. They self-heal for almost as much as the fighter-girl does in one turn, and come in packs of three.
They're just a chore to fight, to the point where I flee whenever I encounter them.
Anyway, those are my thoughts ATM. I'll see if anything else comes to mind as I continue playing.
