Story / Gameplay
This game is about absorping the weaker molecules and in doing so - you gain one of their atoms for yourself. When you reach 29 atoms the level changes and the difficulty ramps up.
You need to avoid stronger molecules. The yellow neutrons are safe pickups - but the blue anti-matter is dangerous.
Yellow and red are both visible on this screenshot - so is the anti-matter.
Number of levels is indicated in the user interface once it unlocks; This is the first to inlock from nothingness, then comes the map in the background and the stars; You’re molecule also starts out as nothing.
