Congratulations on making your game! I really like the look of this and I think it is presented very well.
I'm with Darkgecko on the controls, using the mouse to rotate the character doesn't feel very intuitive and made it harder to control the character than it really should be, to the point where I gave up rather than struggling to make it through the level.
I think you've got a solid base here and I'd love to try again if you do change the controls!
