I found this game actually spellbinding. For a couple of days I did almost nothing but play it and talk about it with some friends who were also playing it at the time. Having now beaten it almost a month ago but not adding it here cause I'm a lazy cunt, I can say I still quite like it. The central mystery is really compelling, and seeing all the characters interact and slowly open themselves up to Junpei was really fun, and theorizing with friends added a lot to the experience. The puzzles are probably the weakest part of the experience. They were not awful, but I found the vast majority really easy and kinda forgettable. The very few ones that actually made me think always told me the fucking answer when I didn't want it and ruined the few moments where I felt clever. I do enjoy the whole digital root idea, it almost allows you to predict a twist or two and what characters you'll be with next, and the game gives you a handy calculator to help with that. My favorite part of the game, however, is the true ending. To get it, you need to play the game at the absolute least twice, as you must get a separate ending that unlocks it. I stumbled unto this one by accident, and after another run where I got a bad ending, I finally did the true ending route on my third run through the game. This route is quite beefy and where you see a lot of ideas talked about in other routes finally pay off in a satisfying enough fashion. I found the final twist pretty clever if a bit spoiled by how much the characters talk about morphic fields before it happens. However, the way this twist was presented was the sickest shit ever and one of the coolest uses of the DS and its double screens I've ever seen. It was probably the first time I've seen them used to enhance the narrative and not just the gameplay. I really don't see it hitting as good in any other platform, even if those versions can be considered superior otherwise.
