My pleasure,
I was theory crafting about this like 1 hour ago and was thinking around the movement stage of the puzzle and player ux over there. It is a bit tricky that stage to have indicators well polished so player can solve it. We don’t want it too hard or too easy.
So its a little bit on your hands and depends how you cook things.
EX: On a right action started being performed something happens to material in beaker. Color changes, smoke comes out, bubbles etc.
good luck and keep us updated.
