This is an arcade style puzzle game, and I keep finding myself coming back to play it over and over again.
The rules are quick to learn, match the colored magnets to create combos and stop them from reaching the top of the screen. There are a couple of other modes which add to the replay value. They are welcomed, but the most fun I've had was in the normal mode as local coop can be hard to organize since this is a PC game.
The music in this game is catchy, but there are only a few tracks. If you only play it on occasion, then this is fine. It is not annoying for long sessions, but can easily become boring.
Overall, this puzzle game works as being simple. It is not overwhelming to learn, and the only thing for the player to worry about is improving on their personal best. This game is perfect for just letting yourself relax while still feeling challenged by the increasing difficulty. I wish more games were like this, because it provides the perfect setting for both a casual gamer and one that is burnt out from learning new concepts of his/her neverending backlog.
