Fun lil game! I thought the controls were ok, but could have been improved. The only thing I didn't like was how unforgiving the hitboxes were. Its usually a good rule of thumb in games to be generous to the player. I have a ship in my game shaped similarly to yours, and the hitbox is a circle only on the body. It makes the game a lil more fun and also creates those "so close" moments that make you gasp out loud!
Overall good game I say! Play mine if you get a chance!
