Nice game!
I would have put a mouse cursor and the ship aiming at it, instead of rotating the ship on the x variation of the mouse... It felt really weird to control the direction like that!
Little bug at the finish screen, the Total points counter only counted the points I had not used at the end, and not the total of points I gathered during the game. It ma not be a bug, and you intended to show a score system based on the points you sacrificed, but it's not clear if that's the case.
Anyway, nice visuals, nice sounds, nice fun! Good job!
