@pixelzoom was looking through the code for other reasons, and noted that there is no renderer specified for the game screen. This is fairly atypical in most of our current implementations, so we may want to address this (i.e. check some different renderers and see if they improve performance and/or appearance) the next time this sim is updated.
Renderers are rarely specified anymore since Scenery generally decides what is most appropriate and there is a query param to override if necessary, see https://github.com/phetsims/joist/issues/221. Closing.
