No game is "too hard" that let's you grind levels before fighting anybody.
Problem is I, like many others, don't give enough fucks to spend time grinding or EV Training in a Pokemon >>Hentai<< Game.
Even in a normal circumstance I'd just call the dev out for being edgy about "challenge" in a Pokemon game. This shit is frustrating to even look at, like Dark Souls 2. It's Hard for the sole sake of being Hard, not for challenge. Waste of time for a few hentai scenes.
And hey Dev, take the criticism instead of being a loser about it. Whining about no constructive criticism in the replies when people are straight up telling you the game is mind-numbingly difficult for >>No Reason<< is good criticism. Tone it down a notch and let some people see your Hentai scenes since that's what they're there for, then up the ante ffs.
Art is good though so good for you. Best of luck in your game regardless of how you plan to move forward with the game.
