This game's biggest pros are the somewhat original concept and the unique design of the LIs, but that's where the good things end.
Despite having an original concept, the plot sticks as close as possible to anime tropes and conventions. If you're an anime fan maybe you can think of this as a good thing, but I can't honestly say that considering how predictable it is.
Just like the anime plot, the MC is an anime protagonist. However, his characterization is badly made. He's supposed to be this sad loner and that's only true for the first 5 minutes of the game, after that, he turns into the typical anime perverted protagonist.
The same can be said for the LIs, they are two-dimensional characters with clear archetypes that do things and react but don't feel like real people (or real, sentient AIs, in this case).
Even with all of that, I could just take it for what it is and enjoy without minding it too much, but this game's biggest sin is the typical useless sandbox. It's not a sandbox in the sense that you have freedom, in reality, it's just a kinetic visual novel with extra steps.
Instead of having everything served to you image by image, you are required to click back and forth so that you can experience the pretty much linear plot. You get some choices here and there, but they exist merely for the sake of having choices. When it comes to major decisions, you have no agency and you cannot influence the plot in any way. There's even one choice when you're given an option to decline this girl who wants to help you do something stupid, which I did because the MC's decision was completely insane, but even after declining, another LI accepts it and you're forced to go along with it.
TL;DR: A nice concept with good character design, but an awfully boring and predictable plot with flat characters and a major lack of freedom and agency. Considering the heavy lack of content, I do not recommend playing this game. It's not satisfactory and feels more like a chore.
