After playing a bit, some suggestions for the nightclub update:
1. Placing a girl on the stage should slow down the progress of her lust meter slightly. This can be used tactically if you have a girl that is close to maxing out but you just need a bit more time for an appropriate customer to become available. The stage is a great idea, I just feel like it's a wasted asset as it doesn't do anything gameplay oriented.
2. The positions of the circuit breakers for the rooms feels a bit rough. They make sense logically but because two of the rooms are upstairs, this makes the upper rooms far more difficult to fix as it puts the rover in a less optimal position. One solution would to be to make the panels directly accessible from the office, but then the rover would serve less of a purpose, which could be an issue. If there were more reasons for the rover to be upstairs it would feel less awkward, but if this were the case I feel it's speed would need to be slightly increased. As it stands, the rover being upstairs is a liability. This just feels rough from a gameplay perspective. Also, some visual indication of a broken panel would help, like sparking or a flashing light.
3. If viable, make Ari's portrait turn angry if picked up while the player is viewing the Diamond room, as a subtle indicator that they are about to make a mistake. Perhaps this could be toggled in the options with the other 'helper' controls for those who don't want an indicator.
