It was a good game (6.5~7/10), but due to the lack of content it wasn't a great game, and that's why I wouldn't recommend it.
I don't even agree that the ending was rushed, it was just non-existent.
The final choice doesn't matter, you don't see anything new, just a flashback video.
I think the only route that was well explored was Noir's, all the others seem like they were missing something more. I don't think all the other girls had enough satisfying scenes, I felt they were inconclusive. It's disappointing after the Ex's entire route you just pat her butt or tickle her and nothing more. Subby had the best scenes in the game, even though she's a secondary character.
And why no best girl Katana route dev-san? why?
