circloO is a colorful physics platformer in a growing circle. This app version contains all levels from circloO and circloO 2, plus brand-new bonus levels! There's also a level editor and already over 10,000 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 the screen 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! circloO Complete features: - Lots of cool physics features: ropes, pulleys, changing gravity and much more! I've included quite a few mechanics for you to discover. - Over 75 fun, growing, ever more challenging levels! Can you complete the six almost-but-not-quite-impossible Hard Mode levels? - There's also a level editor and an ever increasing number of player created levels! - All levels from circloO 2 and the original circloO, plus 28 brand-new levels! - Unique physics puzzles in each level. - Great music and sound effects by Stijn Cappetijn. - Minimalist and colorful graphics. - The game will take most players three to five hours to complete. Level times are saved, so you can try to beat your own highscores and speedrun levels after that! Plus there are thousands of player-created levels to continue playing forever! - Relaxing yet challenging physics puzzle platforming fun! I'm very happy that circloO 2 on the web won the first Crazy Games developer contest out of 200 contestants! It was also third in the Kongregate contest of November 2018. You may remember it from CoolMath Games as well. Reviews: "It’s an excellent game that has a very playful and chilled out approach to the gameplay, whilst also featuring some wonderfully intricate level design. A very impressive puzzle platformer you’ll really want to roll with. Highly recommended." - Free Game Planet "The difficulty scales upwards nicely and you're constantly rewarded for learning new skills as these always come up in future levels." - Jayisgames The game contains occasional ads after a level, which can be removed with a one-time in-app purchase, which supports development as well. Have fun and I'm happy to hear what you think!

Verdict
The clearest difference is rating: circloO at 4.8 against Osmo Newton's 4.1. circloO also leads on review sentiment (89% vs 65%) and ratings volume (2.4K vs 381). Osmo Newton's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence, monetization model and device support there is nothing between them.
