The only plus I can give this game is some creative use of the DS stylus and mic during a few of the puzzle.
The story was dull and predictable. The graphics weren't bad, but weren't anything to write home about. The music and sound effects were par or worse and most of the puzzles were really easy.
Also, the game was short, just a few hours. There is a new game plus option, but there's no way to skip through cutscenes to speed things up and I can't imagine playing through the whole story again just for some minor bonus material like different journal entries...woooh.
I'm usually pretty soft on games and don't rate them harshly unless they really don't bring anything to the table. This game really doesn't bring much to the table so it gets a 4. Definitely not a buy, and bottom of the queue if you wanna rent. I'm sure many other games in your queue will be better than this one.
Trace Memory was quite enjoyable despite the length of the story. The puzzles where very innovative and got my brain working. I completed this game in less than 4hrs but in that time it was worth it. The dialog seemed a bit stiff but the story was good enough to keep me playing. I would recommend this game to anyone that is planning to take a long trip and is a puzzle lover. Don't be prepared to be impressed, but you will have a lot of fun.
