I know this game has its ardent fans, but I don't know, I don't think it's that great. The whole main gimmick of digging holes to trap aliens is slow and convoluted, and even after practicing, I still can't land it most of the time. Not to mention the game punishes you for not trapping any of the aliens by throwing more aliens at you that are almost impossible to dodge, and they don't even reset after you die! Hard, hard pass on this one, even if the game has some historical significance.
