Gravity Refinery
Route raw materials through a factory to craft and refine shapes for profit.
How to play
Gravity Refinery is a puzzle about building production lines. Raw materials drop from the top. You place machines to cut, shape and polish them, then route the finished products to export ports. Each level gives you a budget and a quota: build the machines you need, connect them with conveyor belts and ramps, and get your shapes to the exit before time runs out. The harder you push, the more you make, so optimize every inch of track to turn scrap into treasure.
Tips
- Each machine takes time to process items: plan your layout so nothing sits idle waiting.
- A Polisher turns 2 or 3 of a shape into 1 finished piece. More input, less waste.
- Acid pools and grinders destroy items that touch them. Route around hazards or use them on purpose.
- Build within your budget or you cannot run the level. Cheaper machines cost less but are slower.
