This is one of those rare times where I just deleted the game after reaching a certain point. No unlock gallery. No nothing. F this game.
I can forgive a lot of its flaws... but making a must lose boss that you don't realize you have to lose against and on which you can waste tons of consumables is simply unacceptable. It's terrible game design. It completely fucks over your playthrough, especially when you take into account that any kind of grinding in this game is absolutely horrid.
So yeeeeah. No. Fuck you. Thank fuck I didn't spend a dime on this game, because if I had, I'd have wanted a refund and maybe even wanted extra money on top from the dev for inflicting this piece of shit on humanity.
