I set off to explore pixels which no player has seen before - the mountain in the north-east corner of the forest.
The hardest part was building a ladder beneath the trees. The most important thing is using a hole somewhere to align your feet, so that you can always get back up the ladder easily.
The picture below contains a prototype superbeer-ladder. Here are two tricks for climbing it. First, take off your boots (and probably your weapon too). Second, only walk forward in short steps.
However, the rocks are impassable. I left the beers there.
