Your ship's hyperdrive is offline and your only option is to find energy diamonds to bring it back online. You have to send an unmanded probe to investigate the nearby systems.
You can navigate your probe by moving cursor over beacons. With mouse you may also open doors and move certain beacons. Later in the game you can collect upgrades to your cursor (e.g. Paralyzer, Teleport and Reflector). With these abilities you can clear all kinds of obstacles. Game contains 21 levels each including hard mode variant and also an unlockable plus campaing.
It is highly recommended to play the tutorial levels first!
This game surprised me, and I like it. It seems like a very unique concept, though the control scheme seemed tedious once or twice. I've just finished the cyaneus levels, on easy. level 4/7 is REALLY hard, considering how narrow the middle passage is. I can't imagine what that is like on "hard" mode.
The music is great, I've liked Ceeyaked since I played Within a Deep Forest. Never heard of the other composer, but since I don't know which song is which here, I'll give him credit as well.
Overall, the game plays very smooth, and the puzzles are satisfying to figure out. Since I haven't played further so far, I'd just say: tone down the difficulty on cyaneus level 4/7.
