Thanks Qaos and PeterO.
Liked the trade mark OVOID, CHAPATI (‘and’ filling?), BOARDROOM (director’s cut) and EMBALM (last supper?).
CHERRY
Is the surface and the def PC? This one may not end on top of the cake, I guess.
I wondered if the theme is around death: mask, shade, soul, but I cant see others .Or magic: spells, charms?
A game called Hollow Knight, may be?
Thanks Qaos and PeterO
I see cherry, vessels, bosses, geo, nail are also involved.
DE @2 & 3 – Yes, a visit to the Wiki article on Hollow Knight strongly suggests that It is the key. Well spotted/surmised! Definitely not in my GK sphere ,,,
