Moonlight

Moonlight is two-level PWAD for Doom II and a Boom compatible source port, although GZDoom is recommended. This is a monsterless puzzle map designed by Darryl Steffen (dobu gabu maru) and initially released in January 2019, with the final version uploaded to the /idgames archive in August of that year. It uses the music track "Witchwood Prologue" by on the title screen.

The map is contained twice in the PWAD, with the default MAP01 using soundtrack "Under the Bard's Tree" and the near-identical MAP02 playing "The True You", both by Bjørn Lynne, but the included documentation does not mention the purpose of the duplicate.

Essentials
This walkthrough will give both directions on how to complete the map as well as information on how to understand its symbols. On map start, you'll be facing a cryptic message that says "Puzzle 1". These symbols will indicate the path to take when you want to try and solve the various puzzles. Pressing the wrong switches in a puzzle will cause your health to decrease(indicated by the full moon at the bottom of the screen beginning to wane.) Begin the map by turning around and pressing the diamond switch behind you to lower the floor. This will uncover various planets on the walls. Press the switch for Earth (located to the north) to complete the first puzzle and exit the room. Follow the corridor and pass the blocked gate on your right to arrive at the second puzzle area.

Numbers
This puzzle teaches the player how to interpret numbers. Moonlight's number system is a base-7 with no zeros. Various rooms show the open squares that symbolize each number using candles. Passing through the puzzle hallway will bring the player to three sets of candles on tables. The player needs to add these candles together and select the correct number by entering the teleporter and pressing the correct switch. In this case, the player wants 27, which is represented by 4 squares on the left side and 3 on the right. The player can exit the room by reentering the teleporter and will arrive back at the locked gate, which should now be open if the correct number was selected.

Letters
The next puzzle gives the player information on the alphabet. There's no pattern to the letters, but various corridors will take you objects that will help translate specific letters: red, green, left, and right are all shown. Moving down the puzzle hallway will show a figure on a pedestal with the word "alive" shown in front of him. In the puzzle room, a winged figure represents the word "dead". Selecting the correct letters ('D' is the symbol with the full left bar and the lower 2/3rds right bar, 'E' is the three horizontal bars, 'A' is the single bottom horizontal bar, and 'D' again) will lower the switches and allow you to progress.

Story
The third puzzle gives backstory and allows the player to interpret the various missing letters. The people who left this place behind were given the gift of light. Their king (the Sun) became jealous and exploded, taking their queen with him. Here, the puzzle room wants the name of the king. Entering "sun" ('S' is the backwards small C, 'U' is the two lower horizontal lines, and 'N' is the blocky number 7) will allow the player to progress.

Moonsong
The fourth section forces the player to translate the letters into sets of blocks based on the number of horizontal or vertical marks that are made by the letter. Walking down the corridor will bring the player upon the word "moonsong" with sets of blocks underneath each letter. The first column under a letter shows the number of horizontal marks, and the second shows the vertical. Note that a long letter (such as F or K) will show two vertical marks. A second note is that certain sets of blocks can represent multiple letters. Further along will bring the player to 4 sets of song verses, with the words mostly separated by vertical lines. Up the stairs and to the right of a set of pillars is a hidden room that is meant to show the correlation between number of blocks and number of vertical or horizontal marks. Continue on to the puzzle room but turn around before entering the teleporter. This will show the player their goal: "Sing what we desire most". The correct answer here will be "light". The correct switches (represented by the number of blocks in each column) is: 0/3, 1/0, 0/1, 2/3, and 1/3. Pressing these switches in order will unlock the final gate.

Lightsong
Past the last gate the player will find two more song verses, one on each side of the room. Translate these if you will, then follow the white corridor (use the automap if you have troubles keeping track of the walls). After some twists and turns (and the need to turn around at the end of a large room to find a corridor to the west), you will eventually see the same cross symbol that was on the gates. Walk through this and the next cross to find yourself in a long hallway with large white crosses on each side. You can walk through the first cross on the right, and the second and fifth crosses on the left to find rooms with more text and various cycling moon phases. Each moon phase can be given a number, with a full moon (bright white) representing 1 and a new moon (pitch black) representing 6. These numbers represent the last filled square in each column of the coordinate system given in the previous section. For example, a full moon followed by a new moon would indicate a 1 followed by a 6. This marks the first box of the left column (horizontal marks) and the third box of the right column (vertical marks). Matching this with the previous patterns would indicate the letter "T".

The text in each cross room tells the player a name: stars, moon, and sun. The puzzle room will want the "most sacred name of all". The player will have to press the moon phase switches in an order to spell out "earth": 1/2, full, 1/2, waning crescent (the very small sliver), full, new, waning gibbous (the mostly full moon), and new. Pressing all of these switches in order will unlock a path through the gates ahead. Pressing on the cycling moon symbols will complete the level.

In Memoriam
The second map is a memorial. Various drawings hang around the room, notably drawn by the sister of the author. You can walk through another cross to find a room containing an "earthsong", translating to elude to what happened and what the purpose of the moon may be.
