That's by far my favorite erogame even better than most of completed games that i had played yet. I really whish that in the future versions we may be able to unlock more options of favors or lewd actions. Like giving blowjobs under the tables or handjobs to the customers during the waitress shifs. I simply love it when a game has mechanics that incorporate H options amidst the normal gameplay choices (like Karryn's Prison did very well with its fight scenes, for example) and this game has the potencial to be the best in its segment.
Another thing that's maybe an interesting addition is the possibility of unlocking the option of Agnes masturbating in the storage room in middle of shift (loved the storage room scene that we already have btw, great work). It could even have a probability of someone appearing during the act and interacting with her. I think it's a nice way to add more Otto content.
Believe that adding this type of action that triggers events as unlockables via talent tree (such as kissing waitress and other skills) is a great way to add more intense content but preserving the slowburn pace that we all love in the game.
