Well, it's a basic little game that you've made and I can't criticise you for that. However, with the way that you've fit it all together and the way that the blobs of alien life or space debris destroys part of the ship when you get close, I'm not convinced.
I'd suggest that you make it into some sort of space shooter game with better controls and make the lazers shoot in straight beams, which look like dotted lines. From here, you can despatch powerups and get it into a better laid out setup.
Sorting out the walling of the ship and the objects is a must, as it was very frustrating to see these cost me a lot of life and shorten the game, since that's the whole basis of the game, you need to work on these first and foremost.
The only other thing you could add is a plot and some boss stages - are these aliens that have different attacks, or do you have to destroy huge pieces of space junk that occasionally haemorhage large pieces of debris? Come up with the captain and get a little voice acting (Fro can help there!) and you'll be well on your way to a great little game.
