How to Progress easier with Agnes during Bartending?
1. Go to Config in mainmenue, last option down there and choose "debug mode" Activate this (at your own, may break your game). A menue appears in the top left Corner.
By clicking on the right Tap, you can unlock the gallery. Choose the tab in the left and another options appear.
Like money and Barstats stuff. Scroll down to "corruption" and put the exp slider to the right for pussy, dick etc.
Then play your shift and you will gain faster exp.
You could also move the exp level to 20, but this could break the game. You can also have more levels then 20.
Don't forget to add skill Points, around 45 are enough to get everything. I would recommend to let the drink resistance to 0 as well as breaking her cloth.
For some perks, you'll need a corruption level 25 in order to buy it.
Later in game, there is the shop where you can buy some potions. Drink them to gain faster exp for each bodypart.
Regarding the tipp minigame, use Flirt option on high value customers, there is a perk which tells you the wealthy ones, the just go for a private saison with him. Note: the game is still running during this, so the other ones might be annoyed.
Long story short: use debug, and progress faster. Also, the Cheatcode on OP.
