Here's my next 100% pen project: Space Wars! Arrow keys to move, space to shoot. There are three types of enemies: Blue - normal; they just move closer and closer to you Green - shooter; they shoot occasionally and move closer and closer Red - advanced; they shoot often and move closer and closer to you Avoid the bullets (green) shot by enemies, and avoid getting hit by the enemies themselves.
All scripting by me. First time using my PTE in a project! :D Inspiration to old arcade game where the alien ships move in steps.
