I think I found a solution to make this an iphone game:
Do this on your iPhone:
-Open the game link in Safari (your normal browser, not a private tab). If it's already open, reload it once so it gets the new version: swipe down on the page, or tap the little circular arrow in the address bar.
-Tap the Share button. It's the square with an arrow pointing up, at the bottom center of the screen. If you don't see the bar, tap once near the bottom and it appears.
-A panel slides up with a list of options. Scroll down that list until you see "Add to Home Screen." Tap it.
-A small screen shows the sprout icon and the name "Deep Soil," with "Add" in the top-right corner. Tap "Add."
The only caveat is that I'm not sure the "update game" feature works and we need to test that it's saving correctly.
