Extreme Burger Defense

Description
Extreme Burger Defense is a tower defense game where the player must protect a burger from waves of hungry bears. The player can set up three types of towers: a tower which shoots bullets at nearby bears, a crystal launcher which launches crystals that explode in a wide radius, and a tower which activates a damaging field every so often that also slows down any bear caught in it. The towers can be only built on grass, on tiles unoccupied by trees.
Destroying the dastardly ursines causes them to drop silver and (occasionally) gold coins, which must be quickly collected before they fade. Silver coins can be spent on new towers, on chopping down trees, or upgrading the capabilities of constructed towers. The player's cache of gold coins is retained between games and can be spent in the main menu to improve specific types of towers.
If a bear makes his way to the burger, it will pick up the snack and try to escape with it, and must be killed before it can carry the burger off the screen. When the burger gets successfully stolen, the game ends. There is no ending, and the player's goal is simply to attain the longest time possible.
