The game is great, the theme was especially good, it felt like you really were an astronaut controlling the ship which most space shooters don't really allow you to achieve. It felt kind of bad when I suddenly ran out of fuel near the end of the level without being hit, maybe a danger symbol with a countdown could show on your screen when you're about to run out of fuel. I only managed to get to level 3 but more buttons would be fun when you get used to the layout, although difficult to use at first. Overall, great game and I hope you keep working on it :)
