Oh, hey. That is currently the only title you may get because the collection worth doesn't show properly in the ending screen!
And yeah, there's a plan to make it more visible which groups have treasures available for museum view & selling. (+ lot of other small tweaks and upgrades)
As for achievements, they aren't in the game yet! And as for stats, I'm going to include a tutorial that explains them a bit, or how you should go about them!
ps. the game general concept is mainly by me and Psy, though Penta and bob_esc did partake the discussions, and kentona made bunch of treasures! Clear credits probably inc later, too.
