I found the controls really difficult to manage, but that's not necessarily an issue. It depends if you want it to be difficult and out of control.

So what’s making it hard to control is the momentum of the ship. The ship accelerates really sharply and it takes a little bit too long to initiate a turn relative to the speed it’s travelling at. As a result, rather than gently steering around obstacles, it shoots way too far to the side and then you have to constantly try to avoid overcorrecting and careening into a wall.
The solution is probably to reduce the rate of acceleration and thus momentum of the ship. Run some playtests with different acceleration and speed variables and see how it goes.
I designed the movement to be that way to be analog to a real ship's movement. To make it more controlled I implemented the X button, which slows you down, at a cost: you are easier to hit.
Maybe a way to fix this problem would be to add a fixed top-speed, in which when it is reached, no more accelerating is done.
