My suggestion is perhaps more of an pos-release thing??
Either way, I would really like the possibility to have a BoyGroup too, maybe you could put it in an DLC afterward ??
Also, I really think you guys should explain the basics of the game a lot better, because it took me a some time to understand that i couldn`t release a single because i havent done any research before and needed to unlock things like lyrics and etc, but by that time i was already full of debts and needed to start over (TT-TT).
Other thing I think would be cool is to explain the differences between the staff a little better? Like, who to contract if you want to train the girls or if you want to only focus on fast producing thing. Because it ALSO took me a while to figure it out why my trainees couldn´t train at all.
But besides that, its really an amazing game, looking forward to the official release!!!
OBS: I´m sorry if the things I complained have been explained in the game, but if so, it was so fast or so in between a really long end kinda boring "dialog" that i let it slide, sorry.
