Thanks so much for the feedback!
For the steam release, we are definitely planning to add some settings like you mentioned you were looking for, as well as an in game warning for those with epilepsy.
There are a number of things I think we could allow you to tweak, primarily around the animated and flickering glitch effects that would really improve the experience. If anything else stood out that you would have liked to control in that regard, please don't hesitate to let us know.
