Inspect detailed scientific dossiers for every passed object, including real measurements, taxonomy, fascinating facts, and direct Wikipedia links.

✦ COMPARISON & COLLECTION ARCHIVE

Browse your unlocked objects in the interactive Collection. Compare any two specimens side-by-side with exact scale multipliers to visualize the astonishing breadth of our cosmos.

✦ UPGRADES & POWER-UPS

Reinvest your ring’s area to multiply your tap power. Catch cosmic anomalies and celestial orbs that warp starfield spacetime and surge your growth forward.

✦ MINIMALIST SCI-FI DESIGN
