Jurassic Survival: Prototype #1

Jurassic Survival: https://dl.dropbox.com/u/71737496/JurassicSurvival/index.html

Just completed the first prototype for the game Jurassic Survival.  Forgive my crude stick drawings, but I was not able to find the right images for the game objects at the time.  I will import better images in my next prototype.  The basic mechanics of the gun turrets are there, but I would like to create a wider variety of towers to choose from.  Instead of the current gold every five seconds I should make the player gather resources around the map.  This will encourage more exploring and less sitting in base forever.  There are only two types of dinosaurs at the moment.  Dinosaurs have a set spawn rate of 1 every x seconds, but I should change it to spawn them in waves.  The way the buildings are spawned and moved is not very fluid.  I would like to make them have a build time and not be able to stack on one another.
