Thanks for playing!
For the relic window, do you mean the one that appears when the encased relic shatters with the "Better luck next time..." button?
As for Griddle's sigil text, currently it's meant to be more of a storytelling style rather than strict biology. There are other sigil unlocks that mention things like "kneeling" or "palm" as well. That said, you bring up a good point. I'm considering whether to stick with that style or switch to something like "claws" for consistency, especially since some relics like Scoot's Groove Disc are biologically accurate.
What do you think?
