This is the latest developer diary #17, showing some physics updates, wiring and snapping objects. Lots of programmer art to see as I prototype some of the tools you'll use in the game. This last week or so I've been mostly prototyping some of the tools to get a better understanding of the usability of them. It has been useful because it is very apparent the tools aren't easy to use in their current state.
So the next few weeks of development will be spent making things easier to use, alongside doing some real testing with a few of my students.
