What the publisher says about Cosmo Merge
Cosmo Merge is a relaxing yet addictive space-themed merge puzzle game. Drop celestial bodies into the cosmos and merge identical ones to evolve them into larger, more powerful objects, starting from tiny Asteroids all the way up to the legendary Black Hole! Two Asteroids become a Comet. Two Comets form a Moon. Keep merging planets, gas giants, and stars to climb the cosmic ladder. How high can you score before space runs out? With hand-crafted animated visuals, blazing solar flares, a spinning Black Hole accretion disk, explosive Supernovas and satisfying physics-based gameplay, Cosmo Merge is easy to learn and impossible to put down.

Those are the studio's own words, reproduced as we received them and not checked by us. The feed occasionally describes a different game altogether, so treat it as a starting point rather than a fact.
We have not written about Cosmo Merge ourselves yet. Every game we cover is taken apart and played first, so this page waits until that happens. The game above works either way.
