## What is Inside a Star?

Welcome to "Inside a Star", a mesmerizing physics-based puzzle game where you control the very building blocks of the universe!

Starting with simple Hydrogen (H), drop and merge identical elements to create heavier ones. Follow the path of stellar nucleosynthesis: from Deuterium to Helium, all the way up to Iron (Fe).

But the journey doesn't end there! Once you reach Iron, trigger a spectacular Supernova explosion to forge the heaviest elements in the universe, like Gold (Au) and Uranium (U). Can you survive the chaotic fission chain reactions, prevent a stellar collapse, and uncover the ultimate Cosmic Truth?

Features:

・Addictive Physics Puzzle: Drop and merge elements in a dynamic space environment.
・Cosmic Scale: Start with Hydrogen and merge your way through the periodic table.
・Epic Events: Trigger massive Supernovas and witness dangerous Uranium fission.
・Beautiful Space Aesthetics: Relaxing ambient sounds, stunning visuals, and smooth physics.
・Global Leaderboard: Compete with players worldwide for the highest stellar score!

How far can you evolve your star before it collapses into a Black Hole? Play now and find out!
