Apparently, lots of work.
This Ludum Dare, despite being very fun, is going very differently than I expected. Lots of work on art right now, creating tilemaps and houses and such, but finally getting to the point that I can implement them into them game. Screenshot should hopefully be coming soon.
Creating the areas themselves are the next thing on the list. Then I just need to get the transitions between them worked out.
PS. whiteboards are very helpful for writing down ideas and to-do lists.
