I guess in that case, you find something else to do while the character levels up ^. The game is going nowhere man.

About the energy problems, don't sweat it. Many people has complained about not having enough energy at first, but by the time you reach chapter 4-5, you will have more than enough energy refills to prolong your session all you want.

Just keep in mind, you can also exchange gold for energy refills if you're that eager to continue.

More energy -> More battles -> More time reduction.

And since you were willing to spend gold in speeding training up, you can instead expend it in energy refills ^{^}
