Hey! Yeah, that puzzle turned out a lot more difficult than I intended... You've got to align them so that all the icons overlap in the very middle of the screen. Here's a screenshot of the setup: https://imgur.com/a/94zIIqZ
Hope that helps!
No worries! There are four separate puzzles which you have to complete:
- Aligning the circles
- Selecting words for each sentence of the little narrative with Q and E
- Using the mousewheel to select the mushroom on the centre pedestal
- Using QEZC to change the grid lines so that the centre pedestal and each of the icons are separated by a line, like this: https://imgur.com/54VY8Qu (a barcode will appear when you've got it right)
Then when you do all that, just interact with the centre pedestal to finish!
