Cosmo's Star is the journey of Cosmo on planets with inhospitable life-forms, battling unknown creatures by ... matching 3 colored tiles.  

Unlike normal Match-3 games, there is no tile swapping.  The only way to move tiles is by finding matching monsters beneath the tiles, which causes those tiles to vanish and the above tiles to fall, and any 3 or more in a row/column will then vanish, powering up Cosmo's blaster.  When Cosmo's blaster is charged, he blasts the nearest alien, extending his journey.

Supported Platforms: Linux, Android, Windows, OSX, HTML (Webassembly)
