Purity is a tile based, puzzle game for your Windows Phone. The concept is simple but challenging. You have a series of tiles that you have to navigate through from point A to point B, absorbing them all along the way. Choose your route carefully because once the tile is absorbed, you can't go back (well...almost).
Purity has 60 levels of play and as you progress up the levels, they become more challenging and special tiles (teleports, shields, connectors, etc.) come into play. Each level can be re-playable so you can try to best your score.
Movement is a little on the tricky side. You control your player (a white orb) by pressing and holding the screen to get a 4-way controller to appear. Slide your finger in the direction you want your orb to move. Should you make a boneheaded move or fall asleep at the wheel, there is a rewind feature. Just tap the screen with two fingers and your player rewinds one move. The movement controls do take a little time to get used to but once you get the hang of things, Purity is an enjoyable, "fun to pass the time with" game for your Windows Phone.
Purity is a free, ad-supported game for your Windows Phone that you can download here at the Windows Phone Marketplace.
