:'D LMAO
It's not quite as phallic as it should be, but a good start!
Make a hoe (n, j) by putting two sticks up the middle on a workbench crafting square and two [plank/rock/iron/diamond], one in the top middle and one to the side of that one.
Use this hoe to hoe grassy tiles, which will occasionally result in seeds popping out. Now, make yourself a little farm plot by hoeing some more grass in a place where you want to grow some stuff. Now plant your seeds in those prepared tiles and eventually you will get a wheat crop. Wheat can be harvested and then made into bread.
Some notes: You'll need to keep animals off your fields as they will trample your crops (as will you, and walking over hoed ground too much makes it revert back to normal mud). The crops will grow best if they're near a water tile, I forget what the range is so play around. But they'll grow without water, just slower.
You can also make mushroom soup but you need to collect mushrooms for that.
edit: to use a hoe you right click on the tile rather than left clicking (which will just dig).
This is why I like this game. I'd been stuck at my spawn point after dying and losing loads of ore, it was very annoying. Now I couldn't get back to my ikea laden cave dwelling because of baddies in my way. It felt just like a platform game and I'd got to that point where it was annoying. So I stopped in my spawn point and waited, and right in front of me the most amazing sunset appears with the square clouds just whisping over, it was lovely!
After that a few pigs could be punched on the way home and I got home safely!
DAY 2 TOMORROW
Yesterday I got lost and ended up cowering in a cave which I'd dug out. I had no torches so sat in dark all through the night. Just as the sun was coming up I realised I'd been staring at iron ore all night. Went to go get it and realised it wasn't iron ore at all and was then killed by a creeper :(
The spawning and losing your inventory thing is a bloody nightmare, fun though.
