Second in priority to hints (http://alpha.glitch.com/forum/ideas/1897/), I would also recommend allowing the player to enter some kind of map notes.
Problem: I end up wandering aimlessly around the streets trying to remember where I saw the nearest butterfly or paper tree, wishing I had just written it down on a sticky note.
Solution: Allow users to add a short personal note to their own map about each street. Hovering over the street pops up the note text so I would only have to hover over each street to find where the things are that I want to remember (much like how I find street vendors now)
Recommendations:
- Streets that have user notes have a special symbol, next to the vendor symbol, that can be hovered over. Streets with no note have no note symbol.
- Hovering over the note symbol shows you your note for that road.
- Allow users to also delete a note from a street so the note and symbol no longer appear.
