nothing work ...
Sorry about that, and thanks for telling us. We checked the live build again just now: every file loads and the game starts in a fresh browser, on desktop and on a phone, so we need a little more from you to find what you hit.
Two things stop play on this one. The intro only starts when you click the gold Begin button, keys do nothing until then. And the keyboard only answers after you have clicked once inside the game frame.
It's built for a desktop browser at 960 pixels wide and it saves in your own browser only.
If neither of those is it, tell us the browser and device you used and what you saw on screen (a dark empty box, the intro, or the valley) and we'll fix it.
Sorry it didn't work for you. We just loaded it in Chrome on a desktop, and Begin and Break the ground both responded. Which browser and device were you on, and what did you see after pressing Run game? A blank frame, a title card that would not close, or buttons that did nothing? That tells us where to look.
