In the sprawling, often unsettling world of obscure indie horror, few titles manage to capture the imagination quite like the cryptic artifact known as "Forest of the Blue Skin -Build December- -Zell23-" . For the uninitiated, the name itself reads like a corrupted save file—a jumble of evocative nouns, version numbers, and a handler’s signature that suggests something both unfinished and intentional.
This is not a game you will find on Steam. You will not see it highlighted at a Nintendo Indie World showcase. Instead, "Forest of the Blue Skin" exists in the murky liminal space of private archives, vanishing Mega links, and深夜 (late-night) Let’s Play archives from the early 2020s. It is a piece of digital folklore, and the "Build December" release tied to the creator "Zell23" is considered the most complete, yet most broken, version available.
Make no mistake: this is a slow-burn experience. You walk. You observe. You listen. There are no weapons in -Build December-. There are barely any items. The core loop revolves around environmental puzzle-solving and avoidance.
The "enemies" (if you can call them that) are rare but terrifying. They are pale, elongated figures that stand perfectly still among the trees until you turn your back. Their movement is jerky, frame-rate independent, as if they don't obey the same physics as you do. Encountering one triggers a simple but effective mechanic: don't blink (metaphorically). Looking away for even a second allows them to close the gap.
The forest is a labyrinth. Landmarks shift subtly between saves. That fallen log you used as a marker two minutes ago? It's now ten feet to the left, or missing entirely. This disorientation is deliberate, forcing the player into a state of desperate map-making or total surrender.
Score: 8/10 (Within its Genre)
Forest of the Blue Skin (Build December) is a masterpiece of its specific niche. It takes the "ero-game" stigma and wraps it in genuinely competent gameplay mechanics and high-quality pixel art. It respects the player's time by offering a legitimate platforming challenge, rather than just being a click-through visual novel. Forest of the Blue Skin -Build December- -Zell23-
Pros:
Cons:
Who is this for? If you enjoy retro-style platformers (like Castlevania: Symphony of the Night or Megaman) and you are interested in the specific "monster girl" genre, this is arguably one of the best games ever made in that category. If you are strictly looking for a standard RPG or a visual novel, this will not be for you.
