Rolling a sphere around destructible levels has never been so brain-teasingly hard.
In this game, you play as a rolling sphere whose only ability is to roll. Along the way, pick up the little dots on each level in order to unlock the exit. It seems simple enough, and at first, sure enough it is, then it gets tough.
There are four zones in the game, each with five levels each. At first it begins just as any game of its sort would. Then, all of a sudden, the first five levels are over - and you're given a password. Along with the password is the instruction: "This is the 4th part of the solution to Level X" that's when things get interesting.
With that simple phrase, this becomes not just a bland puzzler, but one with a goal. It becomes a challenge to unlock the code for Level X and complete it. With that simple password code every five levels, this game has something which other puzzlers don't - incentive. You want to beat it.
That said, it's not a simple task. "zone" 3 and 4 are quite the brain-teaser and will have you restarting more than once. Chance does play a part, that's true in some of the levels, but it's the goal which will bring you back. Oh, and as a side note - play with the sound OFF - trust me on that.
