OG Munchers - makes playing the classic Number Munchers educational game possible and easy on Android devices.

OG Munchers is not the game itself and does not contain or require any ROM to play.
OG Munchers simply provides an interface to the publicly available Internet Archive posting of the streaming version of that game found here: https://archive.org/details/msdos_Number_Munchers_1990

This requires internet to load, but does not use any data after that.
