I created this game while I was getting trained by GameDev.tv for Unity 2D game development. Credits to them!

I made some modifications: Wrote an algorithm for creating randomized enemy pathways. In every game session, the route of the enemy hordes randomly changes, to support replayability.

This game will be improved and shared in near future.

Instructions:

Just press "space" or click left mouse button to start shooting. It will continue to shoot after the one of each buttons is pressed once!
