Sum3 progress has been rather slow and not as much content has been posted as I would have liked. A solution to this is to promote the project to students but that seems rather impractical for such a small and featureless project.
The other evening I decided to start working on canvas tutorials and write proper tutorials rather than lessons involving the steps required to make a game. The basic theory behind frames, object handling, collision, logic and mathematics will be some of the items included in the process.
