Until Jay at Jay Is Games pointed out that Hoshi Saga 2 had recently been released, I didn't even know there was a Hoshi Saga 1.
Well now I do. And you do too. Each saga is a collection of mini games, all beautifully designed, that range for the simple to the maddening. Some puzzles simply require clicking, others waiting, and some require a specific movement of the mouse. All with the aim of uncovering a star. The fun is in finding out the proper mechanism.
No puzzle should take more than a few minutes at the very most (often it is a matter of seconds once you know what to do &mdash with the exception, for me, of the one with the thistly things flying about seemingly at random, I was on the verge of throwing things) and the game saves your progress so you can come back to it at any time.
An elegant pair of time-wasters that are well worth playing.
