A Generic Tower Defense

: This is a tower defense I made while in my programming class to show off Game Maker (and hopefully get a couple of people hooked). It came together fairly nicely, and makes for a fun (yet fairly generic!) tower defense game.There are 6 different towers to choose from:* Basic Tower: Starts with a mid-level attack range with an AOE shot and upgrades to higher range, shooting speed, damage, and AOE.* Ice Tower: Stops enemies that it shoots who come within its very small range. Upgrades to longer lengths of freeze.* Poison Tower: A tower that shoots poison darts that will poison enemies into being hurt for a period of time. Upgrades to longer poison time and a higher shooting speed.* Flame Tower: Blasts flames in a radius that will damage any enemy nearby. Good early on, but can be near useless later on. Upgrades to shorter times Between explosions and more damage.* Epic Tower: An expensive tower that shoots quickly and with very damaging bullets. Does not upgrade.* Darkness Tower: This tower spits out small enemy-seeking missiles that will continue to hunt down enemies for a period of time that can be increased through upgrades.
