Making a platformer, you are calm. Adding slopes and there is no god anymore, who can help you.

Also, kinda remind now, Hollow Knight has some sloped ceilings, causing some unintended behaviour (looking at you, vengeful spirit pogo)

You can still play the ascii-version :P

Nope, the text is correct.

not (x or y) <=> (not x) and (not y)
not (x and y) <=> (not x) or (not y)

Edit: The parenthesis on the right side if the equivalence are only there to make it easier to read. Without those, the expression would be the same in this case
