Atomic Reconstruction is a game I wrote originally for LudumDare 36. After the competition ended I fleshed out the game a bit and added more maps.
Atomic Reconstruction is a atmospheric Puzzle game, where you have to use the power of fusion and fission to create and modify specific atoms or groups of atoms.
Combine and split atoms on varying playgrounds by mass and work your way up to the desired Atom, the fewer steps you need, the better.
