What it does

A chemistry spell sandbox, and the first playable slice of a larger game where real skills are the magic system. You gather matter, write real chemical equations, and the simulation decides what happens: water douses fire, electricity splits water into hydrogen and oxygen, and a balanced 2H2 + O2 -> 2H2O makes a sharp pop that lights a torch.

Age bands set the difficulty, from picture tiles read aloud for young kids to full equations for older players.
