Astro Golf now has a Hard Mode! The levels are the same, except that you have to score holes-in-one. You can switch to Hard Mode in the menu. Your progress in Hard Mode and Zen Mode are stored independently.

If your ball is stuck on a planet, you can now reset it: just long press to bring the ball back to the tee.

There is now also a Quit button (easy to forget!), and various little bugfixes here and there.
