Prototype Concept Explanation

The prototype I will be making for this course is a game mashup between 'guess who' and 'space invaders', called 'Guess Invaders'.

Players will play the game using a physical model of a spaceship, a number of physical 'feature' pieces that fit onto the ship (e.g. an antennae, portholes, a laser gun, etc), and a number of portraits of ships with different features on them.
The goal of the game is to stop the spaceship from reaching the bottom of the screen by flipping the correct ship portrait. Players figure out which portrait is the correct one by playing the physical feature pieces onto the model of the ship. If the invading ship has that feature, it will now display that feature on the screen, otherwise the game will indicate that the invader does not have that feature. Each time a feature is placed on the model, the invader ship will move towards the bottom of the screen faster, reducing the time players have to determine which portrait they should flip.
As players place more features onto the ship model, they will get a better idea of which invader they are facing, and will be able to narrow down the invaders in the portraits. Once the player has a good enough idea of the invader they are facing, they can flip a portrait of an invader down. If the flipped portrait matches the attacking invader, the player wins the game. If they guess wrong however, they will lose. Players also lose if the invader reaches the bottom of the screen before they flip a portrait.
