Remember "Adventure" for the Atari2600? If so Indenture will seem very familiar! :) The author programmed this game from scratch in order to recreate the original as closely as possible, so don't look for any graphics/sound imporvements. However he did add some additional modes with new screens/items/etc to play with. (Note: Press F1 after starting the game and read the help text! Starting the game is not done in a usual way!)
