image1132936980.jpgCollider is, at it’s core, a casual physics puzzle. The goal of the 56 included levels is to make all the positive and negative particles on the level to pair up and disappear. When they collide, they cancel each other out and vanish. The first levels are very simple to show you the basics in a tutorial fashion. They don’t stay that way though. They get increasingly complex.

The graphics are surpurb, the physics life-like, and the dynamically generated music really combine to produce a game well worth the $0.99 price tag (a free lite version is available as well). The developer isn’t just sitting on his laurels though. An update is coming with 20% more levels (bringing the total to 70) and a new sensor type that will literally turn everything on it’s head.

While this game, unlike most, will make my Must-Have list and stick around on my iPhone, I do have some suggestions. I would love to see different player profiles, volume adjustment for effects and music, OpenFeint leaderboards by level, and the ability to create and share levels.

Overall, this is a really nice little game from the developer of another of my all-time favorites, Block Drop. If you like puzzle games, I highly recommend both. They promise hours and hours of fun at an excellent price.
