I like what you have going here, but this game is so hard it's ridiculous. I don't blame you, it's hard for a lot of us developers to gauge the difficulty of their own work. The one thing I can think of to make it easier is to slow the rotation of the ship. As it is, all it takes to make the ship upside down is about half a second of pressing left or right, making turning the ship based on these crazy twitch movements I can't pull off myself. It might help to tone the speed of everything else a bit too, less thrust added to the ship, less gravity, too. I honestly think these changes would make it like 100% better. I really do like the concept.

Another thought is to limit the rotation from a full 360 degrees to just intervals of rotation, or some other method of making the ship straight... It's too hard to get it going straight up. But this isn't as necessary.

Hardcore games are fine as long as they have good controls.
Those levels on screenshots...
I am SURE you haven't completed this game.
I suppose this game has narration. Sorry, I couldn't read it all.

Cool game, but insta-death on walls with controls that twitchy is meeeean... The first level though was kinda fun - I'd love to see these controls in a larger, more open environment. I kinda wish you'd gone with your gut, and let me slam that rocket into something at full speed.

What did you use to make this? Are the graphics all done with code?

@Madball: I honestly don't think it seems like it was meant to be hardcore. It seems like what was intended was an exploration, casual game. But if it was meant as hardcore, than by all means, I take my earlier comments back.

Thanks for all of the comments! The difficulty was intended.
In the beginning, it wasn't meant to be too hard, but on Friday I looked at where I was in development, and how long I had left, and noticed that I wouldn't have time to build the 15+ levels that I had planned... So, to increase longetivity, I ramped the difficulty up a bit. I suppose it's a bit too much, now bit, you can cheat, and cycle through the levels with the T and Y keys.
@Puzzlem00n I will definitely make the steering a little less twitchy. The gravity and thrust, might be a little bit harder to balance because I wasn't thinking ahead while coding, but I'll see what I can do.
@Madball I have completed it, but not in one run. After I made a level, I would play it. I completed them all in <20 tries... hehehe.
The last two screen shots are images of the last two levels, (out of ~10).
@gritfish Now that I think about it, it would make sense to have a bit more open-ness in levels.
I made the game in Processing, which is an add-on to Java, allowing one-click compilation, and making visuals very easy to play around with. You can download it at www.processing.org, and see examples at www.sketchpad.cc. No, the graphics aren't all done with code. The ship has 4 sprites (1 not thrusting, then 3 frames with flames) and the blackhole is another sprite that rotates slowly. The blocks are done through Processing's code.

This was just a huge learning experience for me, not only with the time limit, but I also learned a lot about co-ordinate geometry... Meah.
Thanks for the comments. If all goes well, I'll have a new version, with less-twitchy controls and perhaps new levels, sometime in the coming week.
Thanks!
