Here is a game/prototype/demo that I built during my Masters degree. Built using Flash, the concept is a Zelda-type adventure game where story and exploration motivates the player through the game. I have since remade elements of this original prototype in Game Maker and UDK.
Flash proved a powerful tool, and learning Actionscript was an exciting challenge.
I’ve subsequently taken this prototype and used it as the basis for an Unreal design. It is called Nightmare Redux and can be found here.
