Checking off the list:

• Inner maps should be saved in their own file. - DONE
• Having some way to move from one inner map to an adjacent one. - DONE
• Inner maps should only be generated if they don't exist already. - DONE
• The seenFOW map doesn't get rid of old things once they've been removed. - DONE
• Item saving should know whether or not they are equipables - do this via switch on the name I guess

4/5 isn't bad. Feeling ridiculously unmotivated so probably going to do some work on adding features to terrain rather than anything else.

Added some more map generation stuff. Dead trees for desert, bushes for grass land. The world doesn't look so sparse anymore. The fifth bug above needs to be fixed ASAP: can't even use consumables because they're a different type!

Did some cellular automata smoothing on the side areas of the inner maps. Looks not so obviously half-ellipse now.

Also prevented continuing on the title screen if no save file exists. A little polish makes the draft feel a lot nicer.
