There’s good reviews but this game just confused me

This is th best game with beautiful characters. This game underated. Multiple choice of space war game. Unbelievable.


One of the best games I’ve played. The animations and choices are outstanding, and the built in walkthrough is easy to navigate.


im stuck in the ending


I find it weird that they couldn’t include the beginning of the MC’s story into the game itself but had to split it and keep it as some weird side story.

Game starts off kinda confusing, no proper guide or walkthrough to aid you in navigating through it. But once you push pass it, you eventually get the hang of it. Though it’s a little too overly complicated for me.

Sex scenes are dull. It’s almost always the same moves and scenes with just different skins.

But the artwork of the game is top notch, excellent graphics, some not bad music and a fairly decent story to it.

Not a fan of the lack of a harem ending but game is decent enough to earn a 7/10 from me.
