The game looks very good. The mechanic of staying in your shipping lane to maintain your speed is cool. The one problem you may see people struggle with is the tutorial. I've found that putting a bunch of text in front of the player before they play the game is ineffective because they don't understand the context and usually skip it anyways. The easiest way to fix this would probably be to have the tutorial visible on the pause screen but you could also make a whole tutorial level or something.
Overall, good job. This is a cool idea.
