This game is wonderful! As someone who thoroughly enjoys resource-management games, I thought your hotel management system was precise, easy to learn, and very enjoyable! It was addictive to play, although I had some frustration with the janitor:
They are much slower than manual cleaning. This is fine until you max out its levels and realize they are still slower than manual clicking. There were many times I wished I could simply turn them off as I would have been faster. I'd recommend an additional level up at the end that makes them even faster, so that they are at least on par in speed with manual cleaning.
The characters were in-depth, had clear personalities and goals and fears, and very realistic faults. I always looked forward to new scenes and dialogue! Animation is incredibly smooth and attractive, and fetishes are varied! It was fun to listen to the hints given by character on what gifts they would enjoy. I can also definitely see the influence of Persona games in the style of the UI, models, social system, but this style fit this game very well.
Some last suggestions - it could be interesting to have increased customization of the hair and clothes at the beginning. It is also sometimes difficult to remember when you have a room with two types, a primary type and a secondary/additional one (eg. Kinky and hardcore); This is because the icon is both smaller and on the top left corner instead of next to the main icon, meaning the eye passes over it easily. This is a small nitpick, but seeing how good this game is already, some fine tuning like this could edge it closer to perfection!
Ultimately a phenomenal demo with high potential. Highly recommended.
