¹ the usage of "no" in this particular case is a poor example of the correct usage of "no", as endless mode does in fact have additional content in the form of a single rule/tool combo, but not enough content that the developers felt okay stating endless mode had additional content. So here we are, over-explaining a wildly unimportant facet of a chronically under-explained almost-game-demo.
this part is so real honestly. sometimes i'll do this exact same thing don't worry :D
