5	LEVEL		HINT
6	1	STARTUP	Hint: Both buttons need to be held down for the exit to open.
7	2	PRELIMINARY	Hint: You will need to push one of the rocks into the middle pit.
8	3	WORKAROUND	Hint: When in the terminal screen (grey border), press [X] on the red node and move around to draw a line.
9	4	TURNAROUND	Hint: When drawing the line from the red node to itself, pay close attention to which direction you start and end the line. How does that relate to the room you're in?
10	5	LOCKPICKING	Hint: Pressing [X] when your cursor is on a line will delete that line.
11	6	VORTEX	Hint: You won't be able to connect top-bottom and left-right, so you need to find another way.
12	7	GEMINI	Hint: (Two ways to connect the red and blue nodes in a ring) x (Two paths to take) = 4 rocks.
13	8	HEIST	Hint: There's only one direction you can enter the blue room from.
14	9	TANGLE	Hint: What's that new tile in the terminal screen? Try drawing a line on it when there's already a line there.
15	10	WAREHOUSE	Hint: You will need to pack all 4 boxes into the blue room at once before making the switch.
16	11	AIRLOCK	Hint: Plan ahead for how you will navigate the blue room.
17	12	TENTACLE	Hint: Pressing [X] when drawing a line cancels that line.
18	13	TREFOIL	Hint: Take note of which order you need to visit the rooms, and which direction you need to enter and exit each.
19	14	DUET	Hint: Is it possible to connect an edge to itself?
20	15	VORTEX II	Hint: This level becomes easier to manage if you keep in mind that you can only connect top/bottom edges to left/right edges, and vice versa.
21	16	BRIDGES	Hint: When two connections start from the same edge, it matters which was drawn the most recent.
22	17	KNOT	Hint: You will need to draw three different paths over the course of this level.
23	18	CHRONOLOGY	Hint: The order in which you do things is very important. Remember how you solve [16 - Bridges].
24	19	THE VAULT	Hint: [11 - Airlock] may help here.
25	20	PINWHEEL	Hint: Before you search for the terminal solution, don't be afraid to explore, reset, and repeat, until you have an idea of what the rooms look like.
26	21	BIOMES	Hint: The rock that will hold down the magenta button is the rock that starts in the blue room.
27	22	RACETRACK	Hint: Each of the three "tracks" have a unique path in the terminal. Solve one at a time.
