Stacks and Water, Archways, Mirrors and Buttons & Heroes, Duplicated

Spoiler warning: this is a post-game area. You can only reach it after solving the Antipode and the first ending. This page names puzzles and shows screenshots, but does not describe the story.

This page covers four small post-game areas from one solution video: Stacks and Water, Archways and Mirrors and Buttons in the north-east of the High region, and Heroes, Duplicated in the Surface region. The tables give the start of every puzzle in The Flying Chungus video, so you can skip to the one you need.

Stacks and Water puzzle 6, the area's big star puzzle. A tall column of pink crystals is stacked up from a small dark island toward a gold goal marker.

The four areas

The regions come from the video's own description. Its title says 19 puzzle solutions, but its chapter list numbers 22 puzzles across the four areas, so we follow the chapter list here.

What to expect

• Stacks and Water alternates the whole way through: every puzzle is followed by an overworld puzzle before the next one. Its big star puzzle is the last, puzzle 6.
• Archways is short, with four puzzles and two overworld puzzles. Its big star is puzzle 3, not the last one.
• Mirrors and Buttons has only two puzzles with one overworld puzzle between them. Puzzle 2 is its longest, at just over a minute.
• Heroes, Duplicated is the biggest of the four, with ten puzzles. You reach it through an overworld entrance puzzle first. Its big star puzzle 10 is by far the longest in the video.

Mirrors and Buttons puzzle 1. A snowy cliff top with a mirror, a green block and a blue block, two boulders and floor buttons in matching colours.

All puzzles

How to use the tables: “Starts at” is the point in the solution video embedded lower on the page where that puzzle begins, and “Solution length” is how long the finished solution runs. Puzzle numbers follow the video, which numbers each section from 1. They are not numbers shown in the game. Overworld puzzles are listed in the order the video reaches them. You can also jump to any numbered puzzle from the Puzzle Finder.
