I have played and enjoyed the ZE series, but this didn't quite hit the same spot for me. I'll preface this by saying that I definitely recommend playing it, but found that there was much that Uchikoshi left unexplored in the game. There was also a lot of content that could have easily been cut, and many routes seemed a bit pointless. Although entering dreams, the primary mode of gameplay, was quite enjoyable, other parts of gameplay mainly involved a combination of quick-time events, interrogation of suspects and point-and-click. The quick-time events could have been removed from the game altogether, since failing them just gives you a game over and they lack any actual challenge (although I do appreciate the humour that they added to the game). The point-and-click elements and interrogations were poorly-executed, because it was literally impossible to fail them — if you tried to submit clues that were irrelevant, you face literally no consequences because you're immediately told that "it doesn't seem right". This is in contrast to other games with similar mechanisms like the Ace Attorney series or LA Noire, in which bungling your objections or interrogations will cause you to lose "health" (AA) or affect achievements (LA Noire). In summary, while the story of the game is generally good and engaging, it still left quite a bit unexplored or underutilised while including elements that seemed a bit arbitrary, and might have worked better as a straight VN with dream sequence gameplay segments.
