Gamertell has posted a mixed review of Ubisoft's gymnastics game for DS titled Ener-G Gym Rockets.
From the review:
"Ener-G Gym Rockets does get some points for trying. The control scheme is interesting and allows for a lot of freedom. Complicated moves and routines can be pulled off quite easily, provided you've built up enough energy and discovered the proper timing to do it. However, a little more hand-holding and structure wouldn't be a bad idea, especially since this game is designed for children. If Ubisoft and 1st Playable Productions had spent maybe one or two more months developing Ener-G Gym Rockets, I get the feeling that the less satisfactory portions of the game could have been corrected."
