This could be better, a very nice concept with obvious flaws, first of all, we could have less problem choosing idols if we could see their stats with a pop up window while selecting them, or the hability to sort them for their traits while composing songs, and acting, since that's exactly what you want.
It starts well, but when you got more and more material to work with, you really need to have that info on paper or you really mess everything,
The selection screen for choosing songs and idols during a concert could improve too, its kinda annoying to have to scroll to choose everything, I would like a drop down menu or something more simple.
But all and all, we could say this is a decent game, I really don't like simulators, so I honestly didn't sync with this one, still, I find kinda attractive that you should think to work fast or sanae enters to ruin everything, the idea of 2hu characters being idols isn't crazy at all, but I still wonder why Shion has a higher fee than Jo'on, lol.
