Actually, vast majority expects exactly this from almost any porn game, so when the game poses an actual challenge they go bananas
Yes a lot of Porn slop games are just all about dashing around and collecting images/scenes.
This one isn't advertised as a porn slop, so people shouldn't be up in arms about no instant porn and such. It has a slow build up like Karens Prison or Hypnosis Knight-princess.
Not to say "porn slop" games cant be good or enjoyable or even well made, like Future Fragments or Tales of the moon.
