An interesting game, but it gets boring very quickly. This is your first project, so of course no one expects a AAA game and you don't have to give up quickly.
I have a few suggestions that will improve players' gaming experience. First, add a sound when an anomaly occurs, or have the anomalies appear at a specific time. Secondly, if items disappear, they should not be small items so that the player does not have to stick his head into the monitor. Thirdly, extend the time during which information on how to switch the camera appears, this information disappears from the screen too quickly. Add information until what time you should observe the screen and look for anomalies. Finally, I have a suggestion when it comes to the game world. Even if the characters in the game are porn stars, having sex in one position for two hours is a bit unrealistic. Instead, change the style from a pornographic movie to a swinger meeting where people wander around the house and do various activities (talk, eat, have sex, of course, change partners, position and place of sex). Add all rooms, e.g. in FNAF, I mean corridors, entrance doors, storage room, etc. You can also add the same room observed from two different cameras.
As always, these are just my suggestions, you don't have to follow them because it's more important that you add updates to the game regularly, so at least at the beginning, do only what you feel good about and what you love.
