+# This isn't really that great a game. The developer spent a lot
+# of time on bling-ey graphics and sound, but it's missing some of
+# the basic gameplay elements that made Space Invaders a classic:
+# the enemies don't speed up during the level as you kill them,
+# and there are no UFOs (at least, not on the first 7 levels; maybe
+# later?). To be fair, the README says it's "still in development"
+# and not finished (maybe the author planned to add that stuff later,
+# but development stopped in 2007 or so).
+
+# I patched the game a bit to make it less annoying to play (made the
+# intro screens skippable).
+
+# The part of VERSION after the _ is the Debian patchlevel. They've
+# done a good bit of patching and bugfixing to keep this usable on a
+# modern system.
