Digger for your smartphone
Lutz Roeder, the excellent writer of Reflector, had written a game for smartphone, Digger:
Digger is a game for Smartphone 2003. The goal is to collect a given number diamonds and exit the level without getting hit by stones or ghosts. The status line tells you the level, number of lives, diamonds you collected and how many you need to collect. Press "*" to continue after you died. "#" will exit the program.
