Gens (1.10)
An updated version of the original classic arcade shooter with a few new tricks up its sleeve. The premise is the same, though - you are presented with a screenful of aliens, and you must blow them ALL away before they get all the way to the bottom and destroy you.

While it won't trump the simple purity of the original, it's well worth the look.
