Mars Lighthouse: the fish tower

The hall of the four towers

1. Go back to the lighthouse’s first room. Of the five doorways at the top, take the third from the left: lava and floating platforms.

2. Hop onto the platform left of the door, then:
   1. Down ×2, right ×1, down ×1, right ×2, up ×2, right ×1, up ×1, to a door.
3. You reach the hall of the four towers: four walls carved with symbols. A door appears in each as you walk up to it (if none appear, you haven’t used the Mars Star yet). You have to climb every tower and light the glyph at its top; the order doesn’t matter.

Fugue

The lower-left tower (fish)

1. Take the door in the lower-left wall (the fish): a corridor.

2. Follow the only path outside, climb the stairs and cross the bridge on your left. In the bottom-left corner, a door leads into the tower.
3. Go right and up to the next door: icy floor.
4. Step onto the ice heading left, then: down, right, up, left and up to a door: a room of broken pipes.
5. The pipes:
   1. Cast Frost on the puddle on the right side (an ice pillar) and push the pipe on its left to the right so it slots in.
   2. Of the two pipes at the bottom, push the upper one up.
   3. Cast Frost on the puddle between the two pipes and push the top pipe down.
   4. Push the lowest one up: everything is connected, and a torch lights up on the previous screen.

6. Go back, step onto the ice so you slide off the bottom, climb the stairs on the right and step onto the ice heading left again; then down, right, up, right and up, to a staircase next to the lit torch.

7. Stand right of the torch and cast Blaze to the left (it’s easiest when the flame on the wall is closest): the dragon head smashes the ice blocks below.

8. Climb down the stairs, slide off the ice to the bottom, climb the stairs and step onto the ice heading left; then down, right, down and left, to the left-hand side.

9. Go down to the next door and carry on to the outside of the tower. Climb the stairs to the top: a torch and the fish glyph.
10. Stand below the torch and cast Blaze upward: Fish glyph lit.
