All right, here is the next update. The only thing I really have left on the list of stuff to work out is possibly adding moving camera angles, and possibly a difficulty setting.
@Ashingda: I'm sorry you found it so hard. I had four people playtest it and all of them made it around 4 levels into the game. I added a difficulty increaser so the aliens get faster as you beat levels. I hope that doesn't scare you off. This should be a fun remake of the original classic. Just try shooting for the ones on the outside first so they have longer to go before they reach the edge of the screen. If this still is not a good enough tip, please tell me what would make it more fun for you. And stay away from the newly implemented DARK MODE, where you can only see by the light of your shots! Points are more than doubled, but the difficulty rating is super high!
@Rasdini: Explosions added! It was on the to-do list in the Readme, but I felt like the earlier release was enough to release with the promise of updates. I'm not sure why you think the enemies don't fire back randomly... they do, completely at random. Every game "click" that goes by up to 7 aliens have a 25% chance to take a shot. I couldn't do any more than that because the game uses hardware lights for each bullet, and my limit is apparently 8, so...
