is there a cheat menu ingame?
There are patron-only cheat codes if memory serves, which, while I am aware of most of them, they can 1) brick your save if you don't know what you're doing 2) are patron only for a reason, so I'm not going to reveal them.
What I will tell you though, that if you simply skip everything (by either holding down the control key or enabling all skipping options in the menu and toggling it on on android/pc) you'll get through the entire game in less than 3 hours, unlock every scene and every repeatable scene with every character. So that's what I advise you to do.
If you want to still read the story, just get more money, spam the hourglass icon on the top left of the screen, that's the skip time button, and sleep. You get a minimal amount of money for every day passed, and you can reinvest it into the hotel, and then get weekly money from the upgrade in addition to the daily money, which does increase with each additional girl.
