You can currently add a sprite (from an image), and you can build the project file (.prx) like you would from the console, and have it watch for changes on the images using Live Replace (updates the assets in place while the game is still running), and the code having Live Reload (restarts the game on changes).
The inspector on the right is mostly a placeholder currently, but will of course have the usual property editing there.
There’s still a lot to do, but hey, progress is progress!
In Progress
- Game Object hierarchy / tree
- Inspector
