arrow keys to move space to fire
26/02/2017 We're coming close to this being finished. Today I added a bunch of stuff. A background image. Player death when touched by an invader. Sounds. Increasing difficulty. All that's left really is the bases - those little hut things that you can hide behind to avoid getting hit by invader bullets. There is also a bug that I can't track down. If you can survive 4 or 5 waves (which is very hard now that the difficulty increases with each wave) you'll find that you don't get all 50 invaders being created. I can't for the life of me figure out why. If anyone figures it out please let me know!
