Colossal Cave Adventure (also known as ADVENT, Colossal Cave, or Adventure) is a text adventure game, developed originally in 1976, by Will Crowther for the PDP-10 mainframe. The game was expanded upon in 1977, with help from Don Woods, and other programmers created variations on the game and ports to other systems in the following years. [Text from Wikipedia]

Notes for the 3DS release by nop90:

The 3DS console is too small for long text (like help page and credit page) I’ll try to implement some paging in a future release. Running the game on Citra, saving a game fails and exiting the program hangs Citra, but on a real 3DS everything works fine.

The game is released only in 3dsx format because there are some things to test (and probably fix) in the CIA. For the text input I used an old project of mine for a 3DS SW keyboard from 2014.
