Knights in the Nightmare

Back to topic;
So, what do you all mean of, it gets impossible?

Strategy RPG + Bullet Hell. You have to plan out strategies while dodging bullets and stuff.

edit: On topic, I tried Riveira but I couldn't get into it. One, because there was a creepy pineappleing loli bath scene and two because the perfectionist in me wouldn't let me progress without making sure I did each level perfectly and something almost always went wrong at some point.

There are two bath scenes actually...

Perfectionism...ikr? I tend to screw up at S-ranking the boss.
