DiggerME is a port of the classical Digger game from 1983 for mobile devices. It is written in JavaME. The port is based on the Java port Digger Remastered project.
There are two modes for music in the game: TONE and MIDI. TONE is better: it has special effects (when eating an emerald etc.). Unfortunately, it seems to work well only on Sony Ericsson, so the default mode is MIDI. You are welcome to try TONE too!
