There are only 5 levels, but each one is engaging and some are very difficult. There is no real explanation of objective, you just have to go into each level expecting something new and learn as you go. Each one is about solving some kind of puzzle however. The level range from aligning various geometrical objects to make a pattern to flying along a path and hopping through the right portals.
There is a definite spacey feel to the game and it is very surreal. I'd love to see additional levels in the future!
You're also not restricted to completing each level as you go, you can attempt them in any order, which I thought was a great feature.
This game costs $1.29 and is available on the iTunes App Store.
