For the second week, I did a combat game using real-time strategy mechanics. It clones some of the base functionality of games like StarCraft.
You start with a small number of resources and can use those to create buildings and to train units. The units can be created from their respective building, which displays a timer and the number of units queued. More resources can be gathered by using the worker unit to mine the crystals.
The enemy player was done by hardcoding a sequence of actions for creating the building, units; and sending those to mine and attack.
Main Experience: Combat between two armies.
Main Mechanic: Real-time strategy.
