The game definitely fits into a unique niche. It's like weirdly porn-game adjacent but doesn't really seem interested in porn. That's not a bad thing of course, and I actually am really loving the game. But it's fun to daydream about a hornier version.
As to the other half of the question, the idea that there could be evil routes that don't end in Kyou either getting outsmarted, self-sabotaging himself out of idiocy, or otherwise having it blow up in his face is a fun one, if only to be unique. An evil route where he actually wins.
