Known issues in The 2020 Slice:

• • Turret AI is sometimes completely unresponsive.  I do not know why this happens for some people; I hope to have time to patch this issue specifically.

  • Reflections are not present on most/all reflective surfaces.

  • Cubes being pushed by antisoftlock panels in chamber 03 occasionally get stuck (but usually not in a way that makes the chamber unsolvable).

  • If you try, you can softlock yourself in chamber 10 by using a cube to push yourself into the button that unlocks the third room and jumping through the door just before it closes.

  • If you try, you can softlock yourself in chamber 11 by squeezing yourself into the pit under the moving panel in the final room before lowering it.
