DEFEND THE REEF

Enemy crabs will charge at you from the four cardinal directions at once. Control your towers (Arrow Keys or WASD) and manually fire every shot (SPACE). But be wary, because each bullet costs you the same currency needed to buy more towers. Every shot counts.

Waves last 45 seconds. Between waves, you have 15 seconds to decide your purchases. There is no pause button, so you must decide quickly!

Survive all 20 rounds (exactly 20 minutes). 

This is my first game. Made using GameMaker. I hope you enjoy!
