Looking for an old 2D Game

[Erkor]

I remember playing the demo of a game, a 2D sidescrolling puzzle(?) game where you play as a black oil blob with golden eyes.
I remember that you could turn into a puddle of oil to maneuver around and that you could stick to areas.
The game had a single word as a name as far as I remember.
