I think I'm most impressed by this game's commitment to the theme. You think the 'decay' is your ever-sinking colony, and then you're three turns deep without a right-facing piece. You finally accept it, dropping spacers and making do, and then there it is: a right-facing piece. You repeat this cycle, each time whittling away at your faith that the game will give you the pieces you need. Finally, just as it is about to tatter beyond repair, the game throws you a lifeline. You've gotta have faith for the game to erode it, after all.
I didn't play The World Is Sinking. It played me.
