Nice idea, I was happy too se the arrow didn't go all around the place after you shot it, makes it easier to pick it up and continue the fight. With that said, at first I didn't know you could pick up the arrow with your ship, I just thought it respawned or something like that. Also, to make your game more replayable, maybe you could have added an highscore system to incite players in being more invested in the game. WIth that said, nice job :)
