I had some kinda surreal dream about some kind of point-and-click + action game?

The main menu was a collection of tarot-like cards laid out in a circle area. These cards lead to sub-worlds with more cards, which lead to the gameplay stages. On the main hub there were secret clickable areas that switched the screen to some kinda dark surreal horror version with different card imagery. Another clickable area made it a more colourful and peaceful version instead.

One version of the menu screen displayed the words "THE SIGIL OF NOTHING", vertically on the side of the circle.

I don't remember much about the different worlds/stages, but one part of the dream world more realistic/non-game (once again a case of my dreams mixing up if they are "reality" in-dream or not), as it involved someone getting trapped in a collapsed cavern. It then turned out that game was ambiguous in its linearity, in that completing certain stages certain ways would affect later stages. So getting the character trapped under rubble would cause bad-ending routes for some other stages. This was also influenced by if you started the stages in the dark/light surreal versions or not.

Restarting the stage this character/I avoided going in some building/cavern, and there was some other character hanging around, seemingly some villain. I had a bow. I got right to filling this person with arrows. ... this, apparently, was to avoid the result of the previous playthrough of the stage.

I vaguely remember imagery of a character flying on a broomstick as a witch too, basically exactly as things appear in Yume Nikki when you can go for a broomstick ride off the roof of a building. I presume this was another one of the stages/chapters/etc, but I don't remember much else.
