Sorry, I may have used the wrong wording to convey my thoughts. What I meant to say is that I understand that the game might be easier for some, and harder for others, but since Idol Manager doesn't have any kind of difficulty sliders, the developers can't just mess with the game's balance, make it easier or harder, without putting good thought into their actions. Things have to be carefully planned, keeping in mind not only the first hours of gameplay, but also the endgame. Right now, Idol Manager is still struggling to find its balance among the players, since there's people like you who are finding it too hard, and people like me who are finding it too easy. Maybe when the full game comes out, along with a tutorial mode, there will be less people struggling to get through the initial stages of the game, but no matter what they do, at least for now, not everyone will be happy.
Either they come up with different difficulties for the game, or they can simply allow modders to come up with 'Idol Manager Hardcore Mod' or something like that, with an even more challenging experience for the diehard players. The game's current state, balancewise, looks good to me. Sure I'd like an even more challenging grind, but I'm okay with what we've got at the moment. However, it's no use making the game harder, appealing to the hardcore players, if the casual players won't have fun playing the game, and the opposite is also true if the casual players will have a good time, but the hardcore players won't.
