I have to say, they made some really strange decisions with this game, in my opinion.
For starters, whose idea was it to make you click a tiny button in the corner to advance text, instead of just clicking on the giant honking text box? Or really, anywhere on the page not tied to another button. It's annoying. For that matter, why use Unity for this at all instead of something like Ren'py? Do they plan on including gameplay mechanics later that requires using an engine that doesn't have all the quality of life features baked in?
Second, why use Disney princesses if you're not going to use their personality or backgrounds? Is that something that will be touched on later in the plot? I assume so, given that it's called "Princess Quest" and is risking a C&D for no good reason elsewise, but as of now, it's essentially a random D&D party who happens to look like famous copyrighted figures. Well, I guess I can give this a pass when the introduction isn't even complete - but it does need to be addressed at some point.
Third, while it was mildly amusing to say "No, don't go into the cave" and watch everyone give a host of reasons why they shouldn't before being railroaded into continuing the plot... The other times weren't actually amusing at all, so why include the option? I'm not saying that every choice has to be super-consequential, but if the choices are going to be meaningless, at least have them end up in the same place in a way that pretends your input mattered. Like if you choose not to touch the flower, have her trip as she stands up and fall into the flower anyway - don't just go "But Thou Must". Especially not with an obnoxious beep when you choose an option the game doesn't like. I'm assuming that's a bug, but seriously - obnoxious.
Fourth, the plot... Really needs some work. Again, I get that it's a .1, but what's currently presented isn't promising; it does a decent job of distinguishing the characters and establishing their relationships, but does next to nothing to explain the setting, why they're wandering into a dark cave (a rescue mission, yes, but why? Who are they, why are they doing this, and is this something routine or super-dangerous?), or what any of this stuff actually is in the context of the setting. I mean, they pretty much just brushed off what appeared to be a near-disaster with a tentacle plant; surely that justifies at least a little reaction on the part of the party? If one wants to get fancy with it, perhaps use the reaction as a natural way of explaining how much (or little) danger they were actually in - "Who cares, it would have let us go after having it's fun" or "You nearly got us all killed, that thing doesn't stop until its victims die of exhaustion".
This approach makes it feel like "Generic World" at best, and like they're wandering around a set at worst. Nobody is demanding a masterpiece, but it would be nice if one had the impression the author at least tried to tell a story here.
Fifth, I get that it's a porn game, but... Would it have killed the author to include actually sexualized situations rather than just making normal situations sexual? Maybe it's just because the game isn't meant for me, but I can't help but think it'd be a heck of a lot more sexy if, say, the tentacle plant's pollen was suffusing the cave and making them act more sexual in their ordinary adventuring behavior, rather than "Let's look at the rogue's butt while she studies the ground". It ends up feeling like the author was relying on the pictures to do all the work, in which case... Why make it a game instead of a CG pack?
And lastly... It's super, super short at the moment. The CG suggests plenty of work was put in, so I'm not calling the authors lazy, but was there really a point in putting it out this soon? It's not really going to hook many donors interested in the game until there's more to see; in my opinion, putting up some of the artwork they've done as teasers until it's closer to a .3 would have done more to build interest.
All of that said, the artist does seem to be talented. If one is interested in the art style, I imagine they'd probably enjoy it despite these issues. Except perhaps the obnoxious "wrong button" sound.
