Thank you, this is a massive improvement. I might play with this further
to add a config.mk, but still a lot more useful and configurable than
what I had before.

Applied, with one minor adjustment:

> ...
> + rm -f ascii-breakout
> +
> +install:
> + mkdir -p $(DESTDIR)$(PREFIX)/bin
> + cp ascii-breakout $(DESTDIR)$(PREFIX)/bin
> ...

was changed to 

> ...
> + rm -f ascii-breakout
> +
> +install: all
> + mkdir -p $(DESTDIR)$(PREFIX)/bin
> + cp ascii-breakout $(DESTDIR)$(PREFIX)/bin
> ...

so that ```make install``` works even when the ```ascii-breakout```
binary doesn't already exist.
