The group Hokuto Force have established the "Digital Monastery" as their gamemaking section, and this release is based on a 1983 PC game of the same name.

Digger draws its inspiration from the classic arcade game Mr. Do. There is a built in trainer if you want to cheat, or three lives to start with. An extra life is earned every three levels. The basic aim of each level is to collect all the wealth of the mine using your digger. Large bags of gold are also found in each level, and will drop down when the earth under them is removed. When they land the bag bursts open and the gold can be collected. There are two ways to kill the enemies protecting the treasure. Dropping a bag of gold will kill them. The alternative is to fire the digger's bullet, which takes a while to recharge.

Collecting all the treasure dots will complete the level. Killing three enemies will reveal the bonus object (starting with a cherry) for extra points. The music changes and the player must hunt down the enemies. If the enemies are not killed before the music ends, the bonus round is over. If enemies are not challenged for a while during normal gameplay, they may transfer into a Pacman-like digger that will home in on the player and dig through the dirt after them.

This is a pretty good Mr. Do clone. Graphics are bright if a little simple, drawing on the PC original. The music tunes running during gameplay are good, including a nice cover / remix of the classic, Hot Butter track, Popcorn. Difficulty is pitched about right, allowing the player to learn and progress.

Where Mr. Do's tunnels were pixels, in Digger, the dirt is dug away in character blocks, which looks a little simplistic. The enemy sprites are not particularly impressive, and the bullet is difficult to use (especially with its long recharge time). The presentation generally is also quite basic.

A fairly competent conversion of a very old game, which will not last a long time in the memory. The official Mr. Do conversion remains at the top of its class.
