Sorry if this is the wrong forum for a feature request. If it is not, please point me in the right direction. Flyspray used to be (and there are still items listed with a task type of "Feature Requests") but that appears to be no longer true. <http://www.rockbox.org/tracker/task/9891>.
I have an e200 with a very large font configured.
Plugins -> games -> jewels.rock
works well, but the font used is the small default font, rather than the large font that I selected for the system as a whole.
There is only room for the small font (unless the progress bar was narrowed) on the game screen, but the menu screen has plenty of room for larger fonts.
