Our take on Expander

Rather than using combat or platforming as its main structure, Expander makes the player's own shape the central action mechanic. Extending the block opens access to stars, while shrinking it becomes the method for navigating danger.

What is Expander?

Expander is a fast-paced reaction game built around controlling a colored block as it moves through an obstacle-filled space.

Stretch the block to reach and collect stars, then reduce its size to pass between hazards. The game focuses on risk-taking, timing, and quick responses as changing situations introduce unexpected twists. Its central mechanic alternates between expansion for gathering stars and contraction for avoiding walls, creating a continuous sequence of movement decisions.

How Expander plays

The colored block can be enlarged to gather stars and reduced to pass hazards.
02Star collection
Stars serve as collectible targets reached by extending the block during play.
03Obstacle avoidance
Players must adjust the block's size to move safely around walls.
04Changing challenges
Unexpected twists require quick reactions as the game progresses.
