I played a demo a few weeks ago, it was between OK and Great.

User Rating: 8.4 | Pokemon Torouze DS
Although I only played a demo I thought it was OK. But the goals in that mode other than adventure are kind of crazy the plies start to build up, it reminds me of a mix of Pokémon Puzzle League (Which I Own) and Tetris a pretty good mix but I didnt really Love the game a whole lot. The sound was good. Difficulty is Just Right for someone who has played the above games. The graphics are good. I personally like the sound. But if I walked into a Game Store and I saw Tetris DS or Pokémon Trozei, I'd Pick Trozei.
