Notes

By default ruby2d looks for a font only in one system directory -- this is why ruby2d dependency here was forked and patched a bit to support sourcing from the working directory (and $HOME/Library/Fonts).

It can't be compiled to binary right now because of using a Mutex class that is not in MRuby.

It's hard to continue fitting it into 200 lines but I want to add more features -- ~~maybe I'll make a "300-LOC" branch~~ there is now 250-loc branch that has the "next piece" displayed.

Cool font is Press Start 2P from Google Fonts.
