Far better than the first edition, including bosses, power ups, and lots of action! Updated even more for version 4. With extra waves, the bosses are more powerful.A faster fire rate!
An easy and hard mode! (Hard is the original game) Quite amusing, especially the boss. Note: version 5 just released with a bug fix involving hard mode and hard mode has been made more difficult. You now start with 2 lives on hard.
Another update! The game now has sounds, and a few tweaks to the help page. Version 7! correction of a sound bug.
Version 8! Some changes to one of the enemies in hard mode, and another sound bug corrected. Enjoy the game and keep checking for further updates!

Correction: I am no longer able to provide updates because Game Maker cannot handle any updates to the game. Unless someone has a way to reduce the strain on Game Maker or a new version of Game Maker comes out which can handle the updates, all planned updates are suspended.
