These jokes were written in 2008 and you can't convince me otherwise.
The art and character designs are great, but personalities and dialogue is boring and full of tropes and also constantly making fun of those tropes, doesn't work as a dating sim because none of the characters feel dateable at all since all their tropes they consist of are just made fun of. The gameplay is also super random, it's not clear what demands what stat and how and why and I actually didn't even bother to reach any real endings because all I could think about was my time that I would need to invest running down an actual drain. Maybe its more fun in multiplayer because then you can laugh at the cringe together. I don't know.
If you laugh at things like "pooping out unicorns" then maybe its for you. Enjoy
