the game looks very promising, the style and vhibi H is nice, looking forward to more interactions with the girls as the boss, I also think it would be cool if the office had the same animation for chibis than customers but with you doing them there.
I have to agree the time to progress is way too high, I love this kind of games and despite that I got quite bored of the waiting, the time to get a new upgrade shouldnt be beyond 1 cicle/day considering how long they get (relative to the game scale thats it), each cicle should let you have enough to get an upgrade be it whatever imo.
That said I look forward to more!
