This is the first game I've released, and I rather like it. Difficulty wasn't an object during production, but its comfortably basicaly unbeatable past level 30. Parts are *slightly* glitchy, but I'm satisfied with the finished product. Enjoy.
Because people keep asking, there is no limit to levels, the levels are generated randomly as you play. There is also not "One big ship" on level 20, at level 20 the big ships begin being introduced, and the people who get far past there know that they start coming in *large* numbers.
EDIT: Thanks for the frontpage, I'd always laughed at people who were surprised when they got Frontpage for a submission, and now I'm among them.
