It's quite easy to see why this game doesn't have many ratings: it can't really be played. Any attempt to open anything in both .zip files (after extracting the contents, of course) gave me this popup message:
Still, I was determined to play your game and give you a fair assessment. So I downloaded Monogame, opened the file from there, and tried to somehow play it (thought there might be a "test play" button in the program). Didn't work.
BUT while I did that, I dug around the Tumbleweed folder a bit, and found the Tumbleweed application. For future players of this game, it's located here (I opened this on Windows): [folder where you downloaded the game]TumbleWeed\TumbleWeed\TumbleWeed\obj\x86\Debug .
But the application wouldn't open. It would act like it was loading, but nothing would come up.
Hmm. . .
I tried moving it outside the Debug folder into other folders--no luck. Tried moving it into the XKCD Tumbleweed Game folder, putting it in various places there--nothing.
I've tried to open this game for ~30 minutes. Here is where I give up,
I won't rate it out of fairness, of course. Please do better next time at exporting your game. It looks like a cool interpretation of the original comic. But that unfortunately doesn't mean much when it can't be played.
