I'm pretty stuck on this level — is there a mechanic I'm missing with the small box in the bottom left?
As far as I can work out, I need to be able to reset the red stopper in the bottom right in order to exit the level. The assumptions I'm making are:
- The red, blue and green blocks can only move left and right, not vertically
- Once I'm round the corner, next to the exit, there's nowhere I can move the red blocks.
- The block in the bottom left can move anywhere in the bottom half of the level, but it can't go down a 1x1 corridor, which means it can't get into the top part between the red and blue blocks, and it can only block the right-angled corridor in the bottom right.
Confused!
