Re: Do play my tiny two-player game
Rules-/grammar-wise, it all makes sense except Autumn. The way it's phrased, it's hard to tell if you mean only one player gets a last turn, or if each player gets a last turn. (It sounds like the second, but it's a bit confusing.)
In fact I thought it was just one, so this definitely needs clarification.
What will resolve it is clarifying just exactly what "a player" refers to at the beginning of the rule. "The player on turn?" Or "each player?" If the latter, then "this one player" at the end also needs to be rephrased.
