Install GeckoLib first. We found matching files for this game-version and loader setup. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

000.jar
What's new with this mod?
This is a horror mod focused on the player exploring the environment, they are not random scares or creatures chasing you like typical Dwellers. This mod wants to focus on giving the feeling that the old versions of Minecraft gave. Without bothering the player but giving them the feeling that something is not right. The player has the decision whether to advance or not. It is an environmental and psychological mod with surprises that the player will have to experience. The events are completely random and configurable to the player's taste.
What is recommended to play this mod and have a good experience?
I recommend having textures and sounds from Minecraft Alpha or Beta. Classic mods like Herobrine to give more tension and atmosphere. Play it in singleplayer, play it patiently and explore. If you are not comfortable with the default configuration, you can change it to your liking and reset it whenever you want. It is compatible with multiplayer servers (tested by the community itself in previous versions) and there are almost no bugs or errors that can happen with the mod.
