circloO is a colorful physics platformer in a growing circle. This game contains all levels from circloO and circloO 2, plus twelve brand-new bonus levels and a level editor! You can also play levels uploaded by other players from the editor! There are already over 4000 levels created by players like you!

You're a small ball rolling around in a round level. Collect circles to grow the level circle. As it grows, everything stays in the level, so you'll have to avoid and use obstacles in everchanging ways. For example, a platform that was first very useful to gain height, may prove to be a challenging obstacle after the level has grown!

You can only move left and right, so you'll want to use features of the level carefully to jump and gain height. You'll discover all sorts of physics features, such as changing gravity, a sea of tiny blocks, strange contraptions and even planets with a gravity field. In challenging parts, you'll find yourself fully immersed, pressing your arrow keys as hard as you can trying to get closer to finally collecting that next circle. But don't worry: you'll never have to start over a level, so you can always try again really quickly! And I can guarantee you'll feel amazing once you finally manage it!

With millions of plays on other platforms, circloO has been enjoyed by many and I hope you'll enjoy it too! Have fun and I'm happy to hear what you think!
