Had to find a video on RU-vid to rewatch the hilarious ending when Eiki plays pinball. Still have to go back and do the DLC 1 and 2 final fights at some point: keep getting bad RNG on Yuuma and just haven't tried Koishi. We know a farming sim with Minoriko and Shizuha is coming, but wonder if Eiki's little bit at the end is saying a park sim is a future project plan?
Personally, the rematch isn't as difficult. I would still put Koishi Lunatic and Toutetsu above. Your controls only get inverted if you fail the music mini games perfectly. The only problematic part is that you cannot reuse the same ingredients for 20 seconds. Even then the time isn't very strict.
