This version of the good old DOS-game Digger, now on Android, is not a remake, but is based on the Java port (by Marek Futrega) of Andrew Jenner's reverse-engineered open-source version of Digger for DOS. This makes for an authentic Digger experience with exact gameplay, just as you remember it from the good old days. Eg bags will not fall down when moving up on them from below (and you may reverse-shoot when doing this).
The Android port is developed and made available by Runar Holen. It is provided free of charge and with no ads. For more info about Digger, visit http://www.digger.org/
