I tried the game, and while the art that is there is very good indeed, the gameplay-grind is ridiculous, unfun and killing the mood. The art could also use a bit variety, for example in the basic masturbation scene, there could be two different frames, depending on the text description of either clit rubbing or fingering her G-spot. That is not a big change at all, in digital art it should be easily changeable, but would add much in immersion.
Cleaning the bar once should be enough to either buy the outfit or read a Codex volume. Instead of being able to repeat the cleaning infinitely, maybe make it a once a day event that pays 20 credits. Alternaive payment methods for the librarian would be great as well, even if it is just flashing him some tits, the art for that is basically already in the game.
