Circloo

CircloO is a physics platformer in which you guide a small ball around circular levels that grow as you collect circles. You can move left and right, using the level’s features to jump and gain height. As the circle expands, obstacles stay in place, changing how you can use or avoid them. You never have to restart a level from the beginning after a failed attempt.

Levels and physics

The game includes 56 levels that grow increasingly challenging, including six Hard Mode levels described as almost impossible. Each level has its own physics puzzles and mechanics, such as ropes, pulleys, changing gravity, a sea of tiny blocks, strange contraptions and planets with gravity fields. The game contains all levels from the original CircloO and CircloO 2, plus twelve new bonus levels.

Create and play levels

A level editor lets you make and share your own levels. You can also play levels uploaded by other players; more than 4,000 player-created levels are available.

Times and audio

The game takes most players two to three hours to complete. It saves level times, so you can try to beat your own records and speedrun levels. Music and sound effects are by Stijn Cappetijn.
