I adapted the glitch shader from this page: https://codepen.io/ykob/pen/GmEzoQ (if you are going to use it commercially, I think you should ask for the developer about the license)
The other two shaders were just for asteroids and background effect. I realised they were not rendering properly on the final texture just one day after submission, but shaders are working fine.
Cheers!
