Yeah, I agree with you on your points. I think a little narrative comic would help a lot in describing the game and its goal. A lot of people have fun with these games because they’re somewhat common with such gameplay mechanics, but that doesn’t mean others shouldn’t experience game.
I would describe it as a collective incremental game where you do your best to delay the reset of the world that all players share. In most parts you dig mines just to get resources, but there’s a twist: your actions help others reach the end of the game, and no one can finish without the help of others. It’s especially cool when you’ve collected a lot of resources and see on the dashboard that someone has entered a loop; you then spend ALL your resources just to give them a chance of reaching the end before you leave the game.
