This morning I finished all of the basic functionality I will need to complete the game.
^ Rooms are navigable.
^ Each room has its own hotspots that respond differently depending on what item you are using—everything has a description for when you look at it, or touch it, or hold a torch to it.
^ Triggers are implemented—allowing me to do things like open a door when certain conditions are met
Nothing crazy—basic point and click adventure stuff. But it's my first time, so I am happy :)
I've spend about six hours setting everything—I'm estimating another four hours or so to finish out the rest of the rooms.
