A intuitive use of the single control requirement by having automated actions. Visually decent and easy to pick up but tricky to get a perfect or high score, nice way to challenge your mouse control which is pretty cool.
The ship feels a bit like a cursor, and im thinking that perhaps some interpolation or not making mouse movements 1:1 would improve the experience. Im not 100% on that so you are welcome to disagree with me. The score and information perhaps could be communicated better than a box tucked in the bottom right, and do we need to see the time in XX.XXXX format? An integer there would be more appropriate. Finally, consider how people will access your game, is the way you have done it the most appropriate thing that you could have done or are there better alternatives?
Overall, a solid submission and a good first game. Use what you have found whilst developing this game when you make your next one and work on other projects. What did you learn about game development that you didn't know before? Good work.
