Wow! Thanks! This was my first time writing and using a shader, and it's also the source of the shortcomings you point out:
- I can't draw worth a damn and so I hoped that hiding behind the shader would cover for that.
- It took me a whole day to learn how shaders work; that was a day I would have used to make music.
- I went a little overboard with effect and you're totally right: the glitch is annoying.
A couple of more days, and I would have polished out the above. This is the curse of a game jam!
Thank you so much for playing and leaving a thoughtful comment.
