Solve merge puzzles while wondering:

“What will I evolve into next?”

A free demo is available now.

The demo includes Stages 1–3.

Feature 1: Characters and Scores Keep Getting Bigger!

The protagonist begins as a tiny strawberry, then evolves into insects, animals, humans, and eventually even reaches space.

And it’s not just the characters that change.

As you progress through the stages, the characters, backgrounds, and overall atmosphere of the game change dramatically.

Rather than simply chasing a high score, the game is designed to keep you wondering:

“What will I evolve into next?”

And as evolution continues, the scores keep inflating too.

To clear Stage 3, you’ll need an incredible score of 30 billion points.

But the inflation doesn’t stop there.

What awaits beyond that point?

Keep evolving and see the journey through to the very end.

Feature 2: Irregular Shapes and Rotating Physics-Based Merge Puzzles

Every object has an irregular shape based on its illustration.

Instead of being made up only of circles, each character has its own unique shape, affecting its orientation, rotation, and how it gets caught on other objects.

The rules are simple enough for anyone to start playing right away, but the unusual shapes add an extra layer of strategy:

“Maybe it’ll fit at this angle.”

“Maybe I can hook it onto this.”

Thinking about the shapes and how to stack them creates a unique physics-puzzle experience.

The unpredictable physics also mean that every playthrough can unfold differently.

Feature 3: Challenge the Global Leaderboards!

Steam Leaderboards are supported.

Compete for high scores with players from around the world.

Aim for a new personal best on every stage and climb the global rankings!

Feature 4: Track Your Achievements

The game keeps track of accomplishments such as how many times you create a maximum-level character and how many times you merge two maximum-level characters.

You can check your progress directly from the game screen.
