WARNINGSome users have reported issues with the Tips and endings trophies, which are the last ones you'll get. One user had their CGs erased as well. I have no solid solution to this other than keeping spare saves/backups, or playing the game in one sitting without closing it.
The Puzzle minigame is your basic Match 3.
The wiki covers the mechanics.TIME LOOP 1Simply play through. Gender and name don't matter. For multiple choices, I picked the first. Credits will be interrupted and you'll restart from Chapter 1.
Save occasionally because you cannot replay puzzles if you lose. Losing once will give you T #7.
