Great game, but falls short of the original. This was the first mystery dungeon I played and I absolutely loved it. Now after playing many more games in the series and looking at these games with a more critical lens, I find myself agreeing with the dedicated Japanese Shiren fan base. Everything Shiren DS does well, it fumbles at something else that the SNES version did right. The new dungeons are a nice idea, but they're all carry-ins. New monsters? That sounds fun! Oh, they exist impede progress and destroy items...
Honestly just look at the problems listed on this page: https://w.atwiki.jp/gcmatome/pages/2344.html
