How do you get in the temple of light on binweevils?

I only know how to get the circle and the triangle, the diamond is easy and I'm still working on the square lol.

HOW TO GET THE CIRCLE:

1. In the bottle to the bottom right of the screen there is a cork.

2. Take the cork out of the bottle and put it in the bottom hole of the water tank that is sat on the bricks. (this has the circle in it)

3. Pick up the mug that is by the barrel and dip it into the barrel to get some water.

4. Once you have done that hold it over the water tank and it will automatically empty itself.

5. Then, if you look on the left wall of the room you will see 2 bottles one of them has a cork in it.

6. Take the cork out and put it into the middle hole in the water tank.

i'll have to complete this answer later today because i havea lot to do but i promise it will be ready later today so don't go away.
