Making the screen all fuzzy when you slow down or fail a lot doesn't really make it any easier and it already is pretty damn hard to begin with. I only knew there was some way to slow stuff down, because a YouTuber accidentally figured out how to do it. Even if you know where to look for the infograph, nobody will understand that holding down the left mouse button slows down time.
Thanks for playing! Impairing the vision when slowing down the time was very intentional to deter from over using it. I think every single helping functionality should have some kind of downside or limited resource or be made completely automatic instead of having a button. Some people seem to notice and understand the "guide" or time slowing but yeah, I will definitely enhance that somehow if I make a post jam version.
