About the Developer
This is a hentai-spinoff of Oh, Daddy! It started as an April fool's project and became a full game. The two games are similar in their story, with the biggest difference being the artstyle. I recommend playing either one of the two depending on what style you prefer.

Well be-ins I like Oh Daddy, I will give this a try.
I will rate it later

OK so....... First, you can't minimize during play. So you have to play through till it ends at a wait point.
Second, It is just phone texting......... click , bla bla bla decide how to respond, bla bla bla.....
For a first, it is OK at best. And it's nothing like Oh Daddy other that conversational.......
Maybe down the road (if there isn't a washout) it may get better....

the game is mostly waiting for the messages to appear. cant fast forward through the messages (like clicking to make it appear faster)
Also, after a certain interaction, you gotta wait like 12h or smtg till you can continue the game, which is not ideal for a porn game lol.

Guess it knows how to keep you waiting. Sadly, given how long it's been since the last update, as well as recent events, I'm not sure if we'll get more content.
