I choose hell mode, and i normally play in normal mode, also in gallery there is the option to ot black out the rooms, so i would recommend to turn it on. Now a few things, i turn in on after the slime fight, then i didn't lose a fight so i don't know is defeat battles had a pixel animation.
You see the first cheating pixel art animation after the pink hair girl is rescued a second time by the commander. Ater putting like 15 hours into the game, a boring missionary one than you can't repeat or is in the gallery. Everything else is black out, even the first handjob is blackout. This game is not rewarding at all.
