Just another idea, regarding the existing locker types:
The passive locker: have the option to manually eject the captured girl and choose another. Simply cosmetic reasons. No point gain, maybe a slight point loss (cooldown before the automatic points cash in)
The gas locker: have a toggle button so you can manually deactivate them, if you want the heat (to lure more teachers, cops, curious girls in general). Selling and reinstalling them is way to expensive and dangerous, if the heat spikes too fast. So just SPACE to shut off or on.
The automatic locker: have a setting for only shocked/lewd/teacher/cop... also toggling on/off might be usefull.
Any locker: clicking the arrow (indicator which way the girl will leave) should insta-eject (top 3 seconds) the girl so one has the chance to avoid mass panic by miocromanaging ecections (at the cost of points, obviously).
The ideas just keep coming. I just hope you don't spend 80% of your time on creating more exclusive waifus. With time spend on game mechanics, I assume you'd please both the public and your patreons.
