Mr. Do's Castle

The object of Mr. Do's Castle is to score as many points as possible by collecting cherries and/or defeating unicorn-like monsters. The game takes place in a castle filled with platforms and ladders – reminiscent of Space Panic (1980) – some of which can be flipped from one platform to another, much like a kickstand on a bicycle. The player controls Mr.

Do as he collects cherries by using a hammer to knock out blocks that contain them from the various platforms. Empty holes left by the knocked-out blocks serve as traps for the monsters – if a monster falls into a hole, the player can then defeat it by causing a block above the monster to fall on top of it (and additional points are scored if such a monster falls multiple levels en route to its destruction). If the player takes too long to complete a level, the monsters transform into faster, more difficult forms – at first green in color, later blue – that rapidly multiply once they turn blue. The game advances to the next level when all cherries on the level have been collected or all enemies have been defeated.

In Japan, Game Machine listed Mr. Do's Castle on their October 1, 1983 issue as being the second most-successful new table arcade unit of the month.

Gene Lewin of Play Meter magazine reviewed the arcade game, scoring it 9 out of 10.

Mr. Do's Castle was followed up by Mr. Do's Wild Ride and Do! Run Run, both released in 1984.
