Ignoring the jokes I could make for a moment, Dig Dug is a fun little arcade game. I thought that the touch with the music only playing when you move is interesting for a game of its era, and how there’s also an extra strategy to really rack up the points by crushing enemies with a single boulder. Also the fact that the final enemy actually tries to run away means placement of where you are on screen before going after him is important, and in general that’s an amusing AI touch. Final enemy is like “oh shit I don’t wanna get popped!” and tries to make a break for it.
