A great little puzzle game from the early NES era. This game features two game modes. Game A involves having to collect all the dynamite before time runs out, and game B involves guiding the professor to the end of each level while he's sleepwalking. The use of the different colored pillars gives this game its puzzle element, and it can pretty tricky to determine which ones to lower and which ones to raise. There are also bird like enemies throughout each level that can only be distracted with radishes, for some reason. It's definitely a strange game, but that's what gives it character. Hirokazu Tanaka also provides some catchy tunes for the game, much like his compositions for Balloon Fight and Wrecking Crew. While game mode B relies on trial and error and is ultimately disappointing, game mode A still provides a great puzzle game experience.
