What it does

Deltacraft is a spooky, joke-themed release that the author made after Modrinth's long approval process delayed a normal update. The author says AI tools were used in its creation. The mod adds a dark dimension where players search for obsidian cubes floating in the sky. Breaking a cube reveals a heart inside it, and breaking that heart lets the player move on toward escape. The author recommends going into the mod without reading further guidance, since the stated intent is to keep the discovery surprising.

The mod has a set of hazards that matter during play. Acid rain occasionally falls, and false hearts can spawn after a stare of about ten ticks, roughly half a second, after which they die. A railcannon is described as the only tool that kills them, and it is also presented as the gift for escaping the dark world, dealing a minimum of 400 damage. The author warns that the mod can unbalance a world and leave craters or break bedrock and command blocks, so a player should back up the world first. Deltacraft is released under All rights reserved and is not open source. Its Forge build covers only 1.20.1.
