Hey! I am sorry that you got stuck, I thought we tested it enough but clearly we did not. I added a section in the description to clarify what you have to do in a level. I didn't want to spoil it too much in the page description, so here is a more in-depth explanation if you need it:

Each character can "feel" roughly where the ghost is on the map. This is represented by those colored area you saw on the grid. Each grandma have a rough idea of the grid cell where the ghost may be, and you have to triangulate to get an idea of where the ghost is.

The wave patterns are relative to the trap, so if you align each waves, it may not be properly aligned with the ghost but only with the trap. You need to ensure the trap is on the same grid cell as the ghost before aligning. If the ghost move to another location then you have to position again each character.

This trap device is also able to fix the ghost in place for one turn. This mean that if the ghost was about to move but was on the same grid cell than the trap, then it wouldn't move for this term. This would consume a charge and the trap light would become red. Meaning that at the end of the next turn the ghost will be able to move again.

It is not only about positioning the characters at the correct distance, but also about how to move them around in order to control where the ghost moves and where it get stuck for you to beat him :)

Let me know if anything else is unclear.
