Of the 11 hours in the game save that I have, about 3 hours is dedicated to the main story with the Protagonist that you control. I spent roughly a a few hours engaging in the side contents that is offered, which adds no additional succubi other than the ones you encounter as you progress the story. Roughly half of the total playtime were me sitting through slow text scrolls and expositions of a world that the main part of the game really fails to sell itself to me.
I have to asked myself multiple time: "Why are the story spending so much focus on 3 side characters I've only ever played with for less than an hour of actual playtime." It spend so much time covering THREE different subplots that did nothing but set up for future chapters that you probably wont get to since it takes 5 years for the first chapter to finish development. Those could all have been saved to be explored in the chapter where that character was relevant, but here I am, wasting my time watching them just so that there will never be any payoff.
Between the broken gallery (which should've been the easiest thing to developed), the hours of slow cutscene I have to speed pan across, the total of 11 hours of playtime honestly felt like a waste.
The art style, even when the game changes lead illustrator, showed a lot of promise, and the story telling could have been interesting, but the execution of everything just felt like the Dev has no respect for player time, and would rather slap everything they could into the game without thinking whether or not they should.
I play quite a few RPGM games, so the fact that it was 1.7 GB in size, I was expecting something of massive scale like MGQ RPG. But for a game that size, it has so little actual substance it could've been condensed to over half that size and nothing would've change.
