Nebula Forge — idle × puzzle

Beam: match 4 in a line. When it fires, it clears its whole row or column, depending on the arrows.
Nova: match in an L or T shape. Clears the 3×3 area around it.
Prism: match 5 in a line. Swap it with any tile to clear every tile of that colour. If it's caught in a clear instead, it takes the most common colour.
