GreenBulb
A vibrant, single-player jump-and-run game for all ages — skill, dexterity and puzzles across 20 levels.
About the game
Turn shapes into colour
GreenBulb is a fun and colourful single-player jump-and-run game where you are challenged in your skill and dexterity as you solve puzzles and tests of skill across 20 levels.
GreenBulb has the ability to convert a shape — either by delivering a kick or by leaping onto it. Achieving multiple shape conversions without touching the ground results in higher scores.
What you do with a shape depends on what it converts into. It could mean matching a set of dice, solving a cube puzzle, or shooting a basketball. When the challenge for the current level is complete, the next level opens up.
Free to play. Levels 1–8 are free, a fun and challenging experience at no cost. To reach the levels beyond, there is a one-time purchase of the Unlock All Levels item for $2.99 USD, allowing seamless progression through to the final Boss Level.
The story
The Shape Machine
The Shape Machine is an insidious duplication device that operates incessantly. It unleashes upon the world an unending deluge of repetitive forms, devoid of meaning or essence.
Only GreenBulb can save the world from this dreadful machine — and transform its lifeless offerings into things of colour and enjoyment.
