Well, those are personal opinions. Let me share my unbiased opinion, there are better games, but this one is a good time killer. It's simple, right to the point, no stupid combat extending the gameplay just for the sake of it, the art is average (but serviceable), the sex scenes have just the right amount of text, the protagonists and NPC interactions are funny (this is subjective). It's just a funny porn parody on isekai genre.
Oh yeah i see the problem now, return to the house where you got the key and go talk to the girl above the first one. That's kinda on you here since it does say when you finish talking to the first girl that the second one has the second key. After that you will be good.
