I'm stuck in a level 14. (I accidentally closed the tab. Thank goodness for the save function). The one with 3 characters, where one is in an underground "cell", one is to the right with the button to open said cell and the green one on a platform surrounded by water. I can't figure out how to cross the water. Also, I'm worried that using the crate to get the first guy is limiting my options. I'm going to look up a walkthrough.
I wanted to ask if there are red herrings in this game (I think there are). I passed a level with a rotating cross by just aligning it diagonally and platforming both characters across. Level 17 seemed to impossible but the easiest solution (dragging the cage across to the left) worked.
