Side Scrolling Shooter Engine

This is my current game in progress. So far, I have just a basic game engine (not literally BASIC) which I have re-designed so all the movements are done with code, not animation. The result is enemies with (slightly) more random movements. This could be described as a combination of my Asteroids game engine and the Tunnel game engine.

Categories and tags of the game : Arcade, Incomplete, Score-Attack, Side View, Single Player, Space
