I love planetary defense type games! Good fun!
thanks, MGD. I have an itch to develop this further. No promises on doing that but since you appreciate the genre, i would appreciate any ideas u might have for it (probably best to leave them on the regular page, outside of the jam - and the same goes for anyone else). I know i want (at least) an occasional alien entering air space (well, "space" space :) ). Thanks for checking it out.
