Me too, man. The Witness had several of those for me, too.Ah that sounds really, really good! I like it when I have to let a puzzle stew in my brain for a little bit until I can figure it out.
I've had a few puzzles in Baba Is You that left me saying "whatever, there's no way to do this." The next day I'll go back, and 15 seconds in I say "WOW, why didn't I think to try this obvious thing" and I nail it.
It's really easy to fall into the trap of taking things at face value. If you see walls as walls, water as water, goals as goals... You're not going to get very far. Everything is subject to redefinition.
