On the vain puzzle, non vein has to be touched, i got stuck. Two faces was inside the wall, i could do nothing to solve.
Besides this miss. Im really loving this game! ^^
Edit: After a bit more of playing (really liking it btw) i found out: the faces can spawn inside each other and inside the wall (red thing). And if i grab one, how out of screen, and enter on other side, the face teleport, but i didnt test it with this run i get softlock, idk if will work there. i am playing on Web.
