Import / Extract

First try importing the .7z directly into Spark (no unzipping, lowest effort). If it won't open, extract it with an unzip app and take a look: Has a game folder → still a job for Spark; Has a www folder, or js and data folders → use RPGViewer instead and select the folder containing them.

Game synopsis

Atomic Bond Express is a beautifully minimalist puzzle game that combines chemical bonding with path-based puzzling in a novel way, offering a unique experience.

Atomic Bond Express features carefully designed levels and surprisingly deep gameplay, making the chemistry unmistakably solid—no chemistry knowledge required to enjoy the fun of being a chemist here. The experience is joyful, intuitive, and elegantly simple; you can immerse yourself in it, wander through the art of puzzle-solving, and feel a deep sense of accomplishment.
"This fun little puzzler feels wonderfully approachable" — GameGrin
"A chemistry puzzle game that deserves a spot in your library right away" — EDGE

A minimalist successor blending the award-winning puzzle games Bond Push Box and Cosmic Express. Created by emerging puzzle designer Jose Hernandez and published by renowned puzzle specialists Draknek & Friends (Monster Expedition, Bonfire Peaks).
