Night Reverie feels rushed, and incomplete in terms of it's story, and character development.
Give the player more time to bond with the Characters so the ending has more weight to it.
Having additional puzzles to unlock more dialog boxes will go a long way in this type of game.
I'm quite surprised Night Reverie doesn't have a Hard mode where the map is mirrored and the
puzzles themselves are modified. I wouldn't mind experiencing an altered ending in this challenge run. Just think about the possibilities of expanding the game world and its lore.
Despite what I said I still find this game enjoyable even with it's shortcomings.
I suggest buying Night Reverie when its on sale. Who knows you might like it.
