I just finished that game 3 days ago, and I had exactly the same experience. 120 hours even though I could have gotten my fill in 40. I will say though, there’s a 100% optional area called Endless Tower, and you do NOT need to finish everything there. In the free “Thank You” update, they added extra paintings (emphasis on the pain) that have reworked versions of several major bosses. Those reworks are made to be extra hard for level 99 parties and include tons of meta-build-countering mechanics to be even worse. They aren’t worth your time. At all.
