There seems to be some Anna content that's missing. After finding she's lost the vibrator I can get the tail butt plug from Emee & buy the other one, but there's no scene involving either, just the BJ scene (which needs involvement from Anna, BTW, feels stiff and lifeless).
On the subject of the drone minigame, its too grindy. Increasing the base energy by 1 (maybe 2) and the booster energy by 1 or 2 would help greatly. And possibly a really expensive permanent upgrade to the energy by 3 or maybe 4.
The UI for the Computer/Desk area needs a total overhaul. Contacting Tink should be a separate thing from using the computer and should not be under the same menu. And NOTHING should ever be hidden under 4 layers of menu. Perhaps try give it a more computery feel, rather than like cascading dialogue options
