Game Design and Demo Videos

To demonstrate the voice chat, please ignore our (me and my friend) chatter:P



Puzzle Level 1

Game Design

The game design of the toggle plane level is fairly simple. It will act as a tutorial level for players. The floor plan is on the left. The goal of this level is to get to platform B from platform A (starting point). In the floor plan, red and blue rectangles are used to represent the corresponding toggleable planes. On each platform, there is a toggle button that can toggle the plane’s state. If the planes are in the red state, only red planes will be shown and vice versa.

Puzzle Level 2

Game Design

The floor plan is on the left. The goal of this level is to transmit a stream of magical energy from the start point to the endpoint. When the magical energy reached the endpoint, the secret door will be opened and that marks the end of the level. The orange line is used to represent conductors and there are gaps between conductors (labelled by number), When the player steps on the pressure sensor, a stream of magical energy will be transmitted from the start point. And when the energy reaches any unhandled gap, the energy will vanish. Therefore, players need to grip both ends of the conductor to close the gap of the conductor and after the energy pass through the player’s body, the player will be paralysed (i.e., they cannot move for a couple of seconds). Therefore, if a player closed gap 1, it is impossible for that player to reach gap 2 on time. The solution of this level is to handle gaps and pressure sensor alternately by two players.

Boss Fight Level

Game Design

The goal of the boss fight level is to beat a dragon by destroying all the weak spots of the dragon. However, the weak spots are hidden. Players will be given a different weapon. One player will get a wand, which deals no damage, however, it can reveal the weak spots. The other player will be given a magical gun, which deals damage to the dragon if and only if it hits the weak spots of the dragon. And the player can only reveal a new weak spot only if there are no outstanding weak spots. That means he cannot create a new weak spot if the previous weak spot is not hit by the other player. When one player died, he will go into the dead state. The other player can go into the respawn area to respawn the other player. If unfortunately, both players die, the game is over.
