This isn't necessary bad by any means. It's just not all that good either. The models are nice, the environments are well rendered, and animations are a bit rough but decent. I even found the premise interesting and was looking forward to seeing more updates. Perhaps this would be another VN to earn my patronage. Unfortunately, the updates are short, far between and each seems like more about showing off a different reality than expanding on the actual story. This would be fine if it weren't for the fact that the updates are as I said incredibly short. Like someone delving out a comic 4-5 pages at a time. Because of this the reader makes next to no progress with the characters, the worlds they visit, and the overall story. It's 7 updates in and the only thing I can tell you is the father created interdimensional travel, a mysterious agency wants to stop him, they traveled to an incest dimension where probably they left their actual father, and an all females dimension where the men were imprisoned and "forced" to mate with the inhabitants. This was by far the worse part of the story. I'm not kidding, it wasn't exciting in either eroticism or adventure. Oh, and now the characters are in a world where the daughter is famous for ... no clue other than science is very popular there and she's now on a game show at the end.
Aside from that there's the relationships. Oh man. The daughter is harboring suppressed feelings for her entire family. The mother wants her son and daughter so bad she can hardly stand it. The father, well he's stuck in incest world, but the guy posing as the dad constantly says inappropriate shit which gets called out but no one is cluing in and this guy is trying to get some from literally everyone but the mom at this point. And then there's Junior. He's so clueless it would be sad if it weren't so depressing. I've tried multiple runs and made zero progress on any of the family front so if you're hoping for that to happen, bad news, the only thing you'll see will be on incest world between alternat family. That's it.
So how can this VN be improved? Make updates worth our time. If you're going to focus on each world like sliders make it long enough to matter. The longest portion of this game was the all female world and it took four updates to get through what should have just been one large update. I've checked too. The last update (0.6) was only 20 MB smaller than this one (0.7). I'd understand if this is how the author is dropping the public content and made it clear that if you want more content you'd have to be a backer that would make sense, but if this is how the backed VN is being dropped I'd have to say there's no incentive here. The story has gone nowhere and the worlds are pretty boring on all fronts.
I'll have to give this a 3 stars for the premise and chalk up the rest to this not being for me. I wish the dev all the best in finding their audience with this and if anyone reading this enjoys this VN consider backing the project. F95 is a great site to try these titles out but if you truly enjoy something try to show the devs some support.
