eyes.everywhere

Entities in the mod stalk the player from a distance, keeping at least 8 blocks away while watching. Some look like the player, some have a large mouth, and some open doors or tear down walls. The creatures do not move while the player is looking at them, which is why staying still and out of sight matters. A new thread enters the world with several new entities that want to hurt the player, so the content is built around fear and avoidance rather than combat alone.

The mod also adds weapons and items for the fight. A fast-reloading gun deals 5 damage, a sword called Pain is available, a late-game item deals 9 damage, and a clump of flesh is part of the crafting. Glitchorbs dropped by entities can enchant items at random, and some effects can briefly banish monsters, though the result depends on the game version. The author recommends reading the spoilers before playing, as the story is meant to be discovered in order.
