Story:Citadel is a platform game with some puzzle solving elements. The game is centered around a castle, requiring players to find five hidden crystals and return them to their rightful place. Outside of the castle there are outside areas (including a wasteland, a pyramid, a sea and an island).
It really doesn't come anymore old school for me than this little gem. Hours upon hours of play trying to get every single key and explore every room. This will always remind me of my childhood and of my dad.
