Crystal Defense: Alien Waves
Initial prompt
You are a man You can move left and right on the screen. You move with your finger or A/D keys. Aliens are coming Aliens are walking in waves from the right of the screen. They are trying to reach you. You fire automatically When the enemy approaches, your character shoots lasers at himself. Just get in a good position. When you shoot the enemies, the crystal falls You cannot pass over them. You can increase the limits with the crystal once. A new wave starts every 10 enemies The characteristics of the waves, the enemies are faster, stronger. A bonus box drops every 3 waves Go to the box → opens → gives you a random power. Objective: Stay alive as long as you can! The more waves you pass, the better.
