I would have to say that this game is almost perfect. The controls for this game are excellent, this is a game that is very easy to pick up and play. Also you will notice when you play this game that the graphics are very bright and colorful, and that the sound is very beautifully composed. This game would be a perfect one if not for two minor problems. The first being the fact that this game is very very easy, with a difficulty of about 3 on a scale of 1-10. Secondly the length of this game is very short. Most people will be able to complete this game in a matter of hours if they don't collect everything. Luckily this game does offer a relatively high degree of replay value, as well as lots of fun adventure style gameplay as the slime hero, and great strategic tank battles. Over all I would call this the best game ever made, but I would call it a must own if you have a Nintedo DS.
