Background Information:
It is the final match between two powerhouses of the modern gaming world. Mario and Sonic battle it out to find the ultimate gaming hero of modern times.
Game Mechanics:
The Game mechanics that the game will have in it are a health system which deducts health when hit by an object. Each player will have 2 lives with objects that will allow the player to gain lives, gain health via a health object and lose health via bombs and other objects that fall on top of them.
Objects/Sprites:
The game will have objects for Mario and Sonic as well as the wall that prevents the players from disappearing off the screen. There will be objects for the bonuses that fall down onto the players, as well as an object for the way that they players can control Mario and Sonic. The bonus items that will be falling down will also consist of sprites and objects. The sprites will be a picture of the various items and movements that the characters may encounter. There are also platforms that the characters can step on that are off the ground, but they will be moving to encourage more action during the game.
Rooms:
I would have 2 rooms which will change at a certain point in the game, usually when 2 minutes has passed. One room will contain a metropolis background and the other background will have a forest background. The swap in rooms is to indicate that a new level has started with more obstacles in the way.
User Interface:
The user interface will have a play button, instructions and a high score menu to allow the users to know how to play the game, or to start straight away. It will also have music playing, possibly theme songs from both the Mario and Sonic games.
