It does feel quite intimidating to see how much credits are needed to improve the affection levels. And yes, it does feel, well, stupid to not be able to spend energy on anything. That equals income and experience loss. Highly irritating.

One more thing I have not understood is why, when buying gifts, it matters none how much you pay. All gifts give the same ratio of affection points per income spent. It'd make more sense, in my opinion, to get more when you pay more. Pay one for one, two for three, something like that.

And to beat a dead horse: please, for the love of god, do something about the odds of getting new girls when battling bosses. It is insane to grind for the duration of an event and have nothing to show for it. It really can't be that difficult to take into account the amount of times the player has battled to improve the odds.
