This was a really cool looking project, I'd love to see how you made the visuals for this game!
the game play suffers from a few things though, Because you can't aim behind your ship I'm not sure why you can move to the right half of the screen, it makes only being able to shoot in front of you seem like a bug. Also, because the ship was so fast, there was never really any reason for me to feel like I needed to use the shield because I could dodge mostly everything. All that considered, this is still a really solid shooter, good job!
