Haha not at all.
So yeah, here you are standing on a weird platform right? Speaking with a NPC should hint you that you need to get heavier to break this kind of tiles. To get heavier you need more children and absorb them. To get more children, you need to find a "Birth statue", often hints by some peculiar plants.
All those infos are hinted by a NPC, but maybe they were not enough :)
Thank you for pointing it out :)
