The Voice in the news report is quiet compared to the staticy sound in the background.
The menu music is substantially louder then the opening audio. Headphone users especially could get a very unpleasant surprise after the opening ends. You need to better balance the audio.
The beginning of the music in the menu screen does not sound good, the beeping sound is unpleasant.
I feel like the help button is un-necessary as it is, it might be better to just have the instructions on the menu at all times.
There were some asteroids that had glitchy sprites, they broke into the largest type of asteroid.
If you die too many times, when you press space it crashes the game, this feels intended, and I do not like it, especially since it gives no indication that it will crash the game.
The buildup of asteroids is much too fast, to start with there is a decent amount, then after a little bit, you are flooded by asteroids.
I would prefer it if you could move your ship with WASD.
The core gameplay is not that fun and engaging for me to want to play, and the cutscenes/story audio don't really change it that much to me. The core gameplay being spamming mouse clicks is not very fun, especially since you need to move with arrow keys.
The collision shape for the ship felt far too big. Regularly I would have a asteroid take me out without touching my ship, they were around a ship's width away from any part of the sprite. Either your ship's sprite should be bigger to match the collision shape, or the collision shape should be smaller to match the sprite.
