No worries, I do appreciate the input. And really, I would be quite
interested in adding a statistic for how many types of enemies you have
killed. It's not quite the same as what you are suggesting, but it would
encompass some of the benefits and add an additional element to 100%
speedruns, in particular. :)
In fact, I think I'll add that in right now, since it's such a simple thing
to do.
I'm not so much in favor of a full-on database, though. Hexoshi is supposed
to have very little text (and no text at all would even be preferable if it
was possible). To that end, I'd like the lore to be more implied or shown
than explained/told.
