Saving in the browser version requires cookies. It should save fine in the itch.io version. I am constantly updating the game, but the sites I manage the game on should all be up to date. 1.0.6 is the current version (check the title page).
For the dragon blood quest, slay one of the wyrms (the creatures that burrow underground). It will require a steel sword, a bow, or some critical hits from behind and red berries.
We definitely are going to add more hut scenes and exploration. For fishing, we'll have an NPC explain it eventually, but for now I can explain it:
Hit C with the fishing rod equipped or Z next to water to auto-use the fishing rod. It will start fishing.
When it says there is something on the line hit C (or whatever button is shown next to the tooltip if you've changed controls).
This may catch a rusty axe, or it may say wait for it. If it says wait for it, then wait until it says Pull Now and hit C again. You keep doing this until it catches something (the more times this takes, the better the fish). If you hit C at the wrong time, the fish will get away.
