Show HN: Gravity Game

You're totally right. Actually it's a weekend project I've been working on, and I just wanted to see if people would be interested in the concept.

I'll add a better instruction screen as soon as possible.

In the mean time, the goal is to revive potential life planets by dropping green, blue and red orbs on them, and giving them energy by dropping yellow orbs on the sun (dropping is the Enter key).
