This was pretty cool, I like the concept, I just think it's a little janky in some places, but nothing a bit of polishing couldn't fix! For me, on the select ship screen in the begining it was blank, and I just had to wait the 10 second timer every time I died or won and restarted. I also beat the giant ship by just flying in circles around it while my auto turret shot him, so maybe make it so you can't do that lol. Also, just a tip, when you stretch a sprite, it gets that wierd faded look to it, and to avoid this and stretch it cleanly, you can use a nine slice to avoid stretching the edges and stuff! You're definitally on the right track, just keep with it, it has a lot of potential!
