StarMerge

Collect Stardust in a living nebula, drag matching celestial bodies to merge them up the chain (Stardust → Meteor → Asteroid → Planet → Star → Galaxy → Cosmic Core), trigger Gravity Waves for bonus low-tier resources when crafting high-tier items, use two Wormhole boosts to double production, pinch-zoom the merge tree for long-term planning, unlock space stations to expand synthesis tiers, and chase a higher score.
