Its ♥♥♥♥♥♥♥, don't waste your time. There are way better NSFW games out there.

Honestly, I can't complain. I enjoyed the defense part of the game more than the story. The upgrades can become ridiculously overpowered and absurd, making it funny to just play. Wish there was a horde mode. Skipped most of the story, and the R18 scenes were pretty nice. There is also an interactive section you can do. The true path ending final boss was just the chefs kiss, especially with how long it takes and the amount of money you gain to just become absolutely god. Destroyed the final boss in 3 seconds.
