the UI for this is not very optimal but not all breeding rooms are created equal. Room 1 & 2 give you 3 coins and 1 happiness. Room 4 gives you five coins fe.
The pleasure rooms give you happiness / coins based on the star level of the girl inside. Popping a 3 star girl into the face fuck station gives 8 coins. So very much worth it.
But I agree that the UI here could be a lot better. Especially since the NEW tag covers the benefits on new rooms :)
Yeah, I ended up figuring all this stuff out. My points of 2 & 3 are actually not applicable as I just didn't understand it at first.
Really of those 3 suggestions, only 1 would be helpful because it did take me a second run to learn a couple of things. Just like a "?" tooltip or something that you can hover over.
Also didn't realize how the guide in the top right was organized at first, so probably on me for not reading the whole thing before posting.
