Slots form a ring: matching neighbours (last ↔ first too) give +40% Strength each. Tap Place on a world, then the glowing slot.
Permanent upgrades bought with Dark Matter. A Big Crunch resets them. Hold any row to see what it does.
Optional hard runs. Starting one resets your run like a Supernova (and collects it if ready). Reach the goal for +10% income forever. You can quit any time.
Recent events, first finds, Codex milestones and collapses (last 50).
Three separate saves on this device, saved automatically. Keep one as a throwaway to test and reset. Export and Import use the slot you are playing.
Every achievement gives +1% to all stardust income, forever.
