Chase Vault: a game for the Commander X16 by Matt Heffernan
You are a pith-helmeted adventurer trying to collect artifacts from an ancient Caribbean crypt, haunted by the ghosts that want to keep their secrets. Collect all the artifacts in each room and try to make it to the end. There are many locked doors, so make sure to pick up any keys you find! If you collect each kind of native fruit, you will have more lives, so be on the lookout for them in each room. Also, the ghosts are vulnerable for a short amount of time after you collect each voodoo talisman, so you can chase them for a change.
To play, load CHASVALT.PRG and run. You can use joystick 1 or the keyboard (cursor keys to move) if no joystick/controller is connected.
