Its a platformer spelunking game where the object is to collect as many treasures as possible while avoiding creatures and making it to the bottom of the level and the treasure room.
The game was originally released in 1983 on various platforms and this game is identical with a few enhancements. Retro mode is included to be able to play the game as it was originally (which looks like the computer based version C64). Controls arent that bad either.
