Hey Eigen,
Fair enough about the visibility. Ah, I see - the logic is the same, in the sense of being something of a "new" tech applied to an old (or retro) problem, it's cool! Also, yeah, I noticed it mostly in the landscape, between water and land, and so on.
I did find the answer, but the reference to digging threw me off! Haha I also had the club, but didn't try to punch it since the fists had done nothing.
I'll give it another shot once I have some time. Cheers :)
