Heya, no offense taken! These questions actually provide great feedback for some design choices so i appreciate it.
The potion effectiveness is a two part thing. First it is to prevent an infinite pregnancy. You make big money when you're preggo so I'm trying to keep the income semi balanced. Next lore wise, your body builds up a tolerance to the medications as you use them so it takes more each time to be effective.
Yes, the tea is a fertility booster. Meant to call it fertilitea, but forgot to change it before I made the build. That has been fixed. I'm now looking for a good way to show item descriptions.
I haven't done any keybinds since the game is designed around just left clicking your mouse. If this is a widely requested thing I'll look into it. As for the shop popping up, I've reworked all the locations and timers so the shop is a place you go to at will instead of being forced there at the end of the day. The exit X is gone now too with this next update. I redid the UI too for it. Still playing with layout and collecting feedback.
