I really like the movement system, it's simple, but it creates a lot of depth. And having a leaderboard was a very nice touch. I probably would've went for first place, but I found it frustrating when I kept accidentally hitting the edge of the screen because it wouldn't turn fast enough, which I'd say is the only downside to the way the movement is set up. Only other small bit of feedback is that maybe the telegraphs of where the missiles will travel could flash a little bit right before they're fired. Other than that very clean and fun to play!
