craft-rocket 🚀

A factory-builder tech tree in the spirit of automation games: mine and farm raw resources, refine them through five tiers of processing, unlock machines and stations, and assemble the final Rocket — the win condition. 53 classes and 84 actions, all proof-backed.

  🚀 Rocket — the win condition

Mechanics

Machines are level gates. MachineI unlocks tier-3 recipes and station builds; MachineII unlocks tiers 4 and 5. Recipes prove possession of a machine (a hidden Touch* subaction) without consuming it.
Stations unlock better recipes. BlastFurnace, CircuitFab, CrackingUnit, and ReactionChamber each enable faster or higher-yield variants of existing recipes.
Tools deplete. DrillBit, SolderingIron, and PressureValve carry durability that recipe variants consume — spend tool wear to skip grinding.
Recipe variants trade time, risk, and yield. Many products have a Flash variant (PoW-only gamble for throughput), a Crude variant (slower but recovers inputs), and a station-gated deterministic variant alongside the standard recipe.
Byproducts loop back. Slag becomes flux for double-yield smelting; tar refines into wax and grease; sludge feeds catalysts and binders.

Machines and stations

Class		Description
`MachineI`	🤖	Tier-1 assembler. Unlocks t3 recipes and station builds.
`MachineII`	🤖	Tier-2 assembler. Unlocks t4 and t5 recipes.
`BlastFurnace`	🏭	Blast furnace. Enables faster steel and cast gears.
`CircuitFab`	🏭	Circuit fabrication station. Produces circuits in bulk.
`CrackingUnit`	🏭	Cracking unit. Refinery yields more product per oil.
`ReactionChamber`	🏭	Reaction chamber. Stable variants of extract, resin, engine, rocket.

The final assembly

CraftRocket:  🚂 Engine + 🚀 Casing + 📦 Payload + 🧴 Resin x2  →  🚀 Rocket

Or CraftRocketCat — the deterministic variant, run in the reaction chamber with a catalyst.

Install

Install the driver first, then add this plugin — dobj install hot-reloads the catalog, so no restart is needed:

~/.dobj/bin/dobj install https://github.com/dobjlabs/digital-objects-network/releases/latest/download/craft-rocket.pexe

Or build it from a checkout of the repo, then install the archive:

cargo run -p pexe --release -- build examples/craft-rocket   # -> target/pexe/craft-rocket.pexe
~/.dobj/bin/dobj install target/pexe/craft-rocket.pexe
