Developed by Ocean, Mr. Do! arrived on the Game Boy as an action game. It blends action and puzzle elements.

It is part of the Mr. Do! series. The series also appears on other systems with Mr. Do! (SNES) and Mr. Do! (2600). Ocean also made Jurassic Park, The Flintstones and Jungle Strike for the Game Boy.

Mr. Do! is a single-player game, so it's one to enjoy at your own pace.

Pick it if…

  • you want to fight, blast and test your reflexes
  • you have time for an evening or two (roughly 1–6 hours to see it through)
  • you've played the Game Boy hits and want something less obvious

Maybe skip it if…

  • you prefer slow, thoughtful games over reflex tests
  • you are looking for something to play with friends

What playing Mr. Do! is like

Action games test reflexes and nerve. Expect fast enemies, tight controls and stages you clear by reacting quickly and learning enemy patterns.

Tip for newcomers: Retro action games are often short but tough. Treat early deaths as practice runs; every attempt teaches you where the next threat comes from.
