For my casual game I am proposing a top down view maze game in which you guide your player (represented by a dot for example) through a maze to the goal whilst being chased by an enemy. If the enemy touches you; you die, if you touch the maze walls your health depletes and you die.
To make the game progressively harder the maze could agitate, rotate, change colour, invert and speed up or slow down, this will also create an element of disorientation for the player.
Player movement is directly mirrored by the movement of the mouse, and no other controls are needed.
Initially I was going to make the game using Flash Action Script 3, but have now decided to use Unity instead, this will enable me to import 3D assets that can be made in 3Ds Max and should enable me to give a better look and add more dimension to my game fragment. Using Unity I also hope to achieve a more polished look to the game which would in turn give a more satisfying experience to the gamer.
