Part of me is convinced that the genius of this game is that it can be completely operated with only one thumb, even while riding a crowded subway.
I think I recall the original one featured an helicopter and ran on an Amiga, or something of the sort.
Actually, the first thing I did when getting my first Android phone about 4 years ago was downloading a version of SFCave for Android, and it's been on all of my subsequent phones ever since.
