Sure!
First: a bugfix update, focusing on the most pressing stuff like the save data problems
Then: improvements to the room and script editor + better documentation
Also (relevant for the game that I'm making): Better text rendering support, probably as an html overlay over the canvas or a text box next to it.
I also want to make some public facing project documentation, like a Trello board / google spreadsheet / roadmap / github wiki / github issue tracker. (Not all of these, but at least something for tracking bugs and something for upcoming features)
