The bar got updated - good, but not enough. I can be hated for this opinion, but:
In comparison to Receptionist and Stripper jobs, bar is still quite complicated as it requires a lot of clicks and each action takes a little in-bar-shift time and grinding bar for 25 mins overall is much longer and more complicated than receptionist job for 50 mins.
There should be more extended and exclusive bar harassment scenes that spend more in-bar-shift time and removes the anger of patrons because of Karryn being harassed as it's a public place and everyone sees that. Perhaps Karryn could do a small under-table blowjob, sit on someone's lap while kissing other guy and being groped by the third one. Bar is not that rewarding in terms of content in comparison to other jobs.
Some rework is required, but I doubt that Rem have plans for that as it's just complicated and maybe not worth at the current stage of the game.
The game itself is a huge success for its creator, but bar and lack of professions on levels 4 and 5 is a bit underwhelming. Levels 4 and 5 are done without any inspiration overall, as if Rem wanted to finish the game as soon as possible and no longer desired to make it more complicated than it is now - I can understand that and not blaming him and I hope that he got some learnings from this. I wish him a huge success with the next project.
