Didn't do a lot, but I've extracted the graphics I'll use. Also I did some improvements and bugfixes to my map editor. It only allows simple edition but it looks nice, desn't it?

The transparent pink issue is a bug I'll fix later.

Anyway, I have the gameplay almost designed. Some of the tiles can be removed and places, but some others can't be modified. Also, some of the tiles will trigger character actions. For example, the vines will be used as ladder always, if a character finds a gap it will try to jump it, if finds an obstacle (i.e. a wall) it will turn around, etc.

I think my entry will not be a full game, but will allow to experiment with the concept. And it may be fun too.
