How do you play?

There are two things that really bug me here. Namely, those vibrating things I choose to describe as walls. They're a tad distracting and I fail to understand why they are there. You might consider doing something with them, but that's really not something some random on the internet should have a great say in.

There's also the issue of controls. You should really consider putting a description or an additional screen stating the controls, because I still don't know what they are. Is it supposed to be the arrow keys? WASD? Does the ship's nose follow the pointer, or does it move with the scroll wheel? All of these seemed to do something and nothing at the same time.

Thanks for reading this whole thing, and I'm quite sorry if I came across a bit harsh
