I was randomly recommended the preview build of this game on YouTube, so I'm obviously missing out on an lot of the fun stuff. But from what was shown on there, it's pretty good as an proof of concept.
The vent scene genuinely got an laugh out of me (props for being original in an saturated market), along with the horrifying shit that the brothers were getting into. Speaking of which, it's an bit of an missed opportunity on her not commenting on what they did to her. As for the collectible pinups, I'm kind of on the fence about it; but it's basically an nonissue. Almost feels kind of random, in a way; but hey, it's an porn game. So far, the only sex scene that I've seen was one of the shower events and the animation felt kind of stilted, in a way. But keep in mind that I saw it on xvideos, so I have no idea which build was it.
So anyways, I genuinely hope that the rest of the game doesn't stays completely linear, but then again, we're on an freighter, so yeah. Only thing that's probably missing is some more decorations or something. Because outside of the occasional poster in the furniture in the opening area, it doesn't really felt like it was either "lived in" or that the ship was recently built and more or less stayed that way (outside of the occasional woman that's conveniently exposed in a wall of alien goo). But I'm probably asking for too much, lol. Really hope that you'll deliver on the NSFW stuff, since you did an great job with the MC's design.
