Labyrinth

The Umbral Labyrinth is the sixth level of Monster Girl Dreams. It is a subterranean checkpoint made up of mysterious dark hallways protected a quartet of Hellhound guardians - Ceris, Beris, Ushris and Iabel - who serves as the final obstacle before the hero can reach the monster girl capital.

This is the final level available in the game's current build.

Entrance
The Labyrinth is unlocked by clearing the Caverns. This location plays differently from previous levels, as rather than go through a series of battles and events, the player must instead navigate a maze in a grid map, looking for keys and avoiding both the monster girl guardians and floor traps in order to make their way to the next floor. Before they begin navigating the Labyrinth, Ceris will offer you a tutorial so that you can get used to the controls and mechanics. Perpetua also makes an appearance, baffling everyone and scampering off before anyone can do anything about it.

First Floor
In the first floor, the player will be hunted by Ceris. The floor is fully visible.

Second Floor
In the second floor, the player will be hunted by both Ceris and Beris. The floor is fully visible.

Third Floor
In the third floor, the player will be hunted by both Beris and Ushris. Halfway through the exploration, the map will become partially obscured and the layout will change, adding new invisible traps, keys and dead ends.

Fourth Floor
In the fourth floor, the player will be hunted by Iabel. The map is obscured from the start, the layout is far more restrictive and the traps are invisible, making it harder to avoid Iabel.

Outro
After the player clears the fourth floor, the Hellhound sisters will congratulate you by giving you the Capital Checkpoint Gem and a Lucidian Passport, finally granting you passage into the fabled monster girl capital.
