This game is overlooked. It puts a new spin on the adventure game genre with a 4 character mechanic utilizing both long and short term memories. Basically you use the character's prior knowledge (memories( as tools in the environmental puzzles, as opposed to relying solely on contrived or forced inventory items that might be included in other games.
It is highly innovative which deserves praise in itself, but one of the most amazing feats of this game, is in spite of having 4 characters with various memories, I used a walkthrough maybe a single time on this game. To say a little about me, i'm a fan of adventure games, many classics (too many to list, but to give you an idea: Gabriel Knight, Sam and Max, Day of the Tentacle, Broken Sword, The Longest Journey, Monkey Island and many, many more. However, most of thet ime I resort to a walkthrough to varying degrees when I get stuck.
The story was compelling all the way through and art style really captured the mood. I wanted to leave this review for long time adventure game fans, to not overlook this game.
