Fly up and down and get as many blocks across the 5x3 grid as you can. Dodge greys, though.
You start with 250 fuel. Moving up and down requires fuel, moving left and right does not.
The ship will glide down slowly when you don't move it up/down, or when there is no fuel left.
Mind your fuel level and refill it with Powerpellets, or you'll be stuck to the ground.

Controls:

- Move left/right - mouse. Yaaaawn.
- Move up - left mouse button.
- Move down - right mouse button.

Colored blocks:

- Build up your combo chain. If you miss any, the combo will be broken.
- Colors indicate their vertical position, for easier aiming: yellow on top, red in the middle, purple at the bottom.
- Yellow and purple blocks are worth 100 points + combo bonus, red ones are worth 250 + combo bonus. Hm.

Greys:

- Break your combo. And your stealth. And take away 1000 of your points.
- That's about it.
- Oh, and when the stealth is broken, an irritating sound is played. So, you better avoid those.

Powerpellets:

- Are usually found at the songs' best parts. Or so I heard.
- Their positions are also marked on the minimap.
- Add 250 fuel, increase your combo by 25 and give you 5000 points. You're welcome.
- Always spawn at the lowest row, so if you're out of fuel, you can get them.

Bonuses:

- Stealth (30% bonus): for hitting no greys.
- End Chain Bonus: length of the last combo chain you made, times 100.
