Physics-based iPhone puzzler A Moon For The Sky, along with A Moon For The Sky HD, is currently available for free.

A Moon For The Sky is set during the dawn of a new millennium, just as the moon is about to perish. You're tasked with lofting a new moon into the heavens to replace it.

To do this you have to drawing lines with your finger, bouncing the moon repeatedly skywards, collecting stars, and avoiding obstacles along the way.

A Moon For The Sky features 18 progressively more difficult levels, unique physics, relaxing melodies, and an endless mode for highscore play. Global leaderboards and achievements are available through Game Center.

We gave it a 6/10 at review.

We've contacted Bulkypix to find out how long the offer will last.
