Game Mechanic
The core game mechanics is deciding how the placement and upgrades of the dungeons are used. It boils down to managing resources in a correct way by balancing upgrades in the dungeon and on the hero. This will ultimatly result in one person having a better strategy and finsihing the others dungeon before their dungon gets finished by the opposing player.
Camera View
This game will have to have 2 types of camera views. One will have to be bound to a character (the Hero) and the other will have to move when the mouse hits the edge of the screen as a panning motion.
AI
All the monsters and turrets that are placed by the player will need to have AI. They will have a range where they can see the player and then engadge the player and try to kill him with either a long attack or a melee attack. So the monster will also have to be able to decide where to move to. There may also need to be Ai that can do everything that a player can do to create a single player mode.
Physics.
The hero and all the placebal objects should directly be able to collide with one another. An attack should have a knock back and equal reaction to what it is hiting.
Audio
All the monsters and heros will have sound effects for attacking and moving. There will also be sounds for placing things and the occasional idle sound. When changing the inviorment there will also be a sound.
