Drill Dozer marked the first time Ken Sugimori directed a game since Pulseman eleven years earlier in 1994. In a 2005 Nintendo Dream interview, he revealed that due to the increasing amount of content and collaboration required in making modern games and much of Game Freak's newer staff only having experience in the Pokémon series, he was prompted to place his full trust in the younger staff for most of the gameplay development as he realized he was not as young as he used to be. Sugimori scaled back his efforts to focus on drawing art for the game while character designs were done by Hironobu Yoshida. He also noted that Drill Dozer gave him an opportunity incorporate ten years worth of ideas from previous games that went unused due to memory constraints or deadlines, and felt they succeeded, which gave him a sense of relief.
