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!

How high can you climb? Free Climb is easy to pick up: tap a hold, move a hand, climb a little higher. But reaching the top takes a plan. Big holds are easy to grip. Small ones tire you out fast — and if your energy runs out before the top, down you go. Pick your path, pace yourself, and keep climbing. Try to keep one hand on the wall, lest you fall. Every wall is brand new, made fresh just for you — and every wall is guaranteed to have a path to the top. Finding it is the fun part. EASY TO LEARN, TOUGH TO MASTER A quick, friendly tutorial teaches you everything you need. The first levels are a breezy warm-up; the later ones will make you think about every single move. Feeling bold? Leap for a faraway hold — catch it and it's glorious, miss it and you're falling. COLLECT THE GOODIES Every wall is sprinkled with treats worth a little detour: snack bars that refill your energy, a chalk bag that keeps your grip from slipping, carabiners worth points, and an extra life if you can reach it. Grab every goodie on the wall and finish the climb to double your points. UNLOCK NEW PLACES Your points add up with every climb you finish, unlocking harder levels and whole new places to explore. Start out at the Climbing Gym, then earn your way to Joshua Tree — a sunny desert of red rock with taller walls and bigger rewards. More places are on the way. READY to start your ASCENT TO NEW HEIGHTS?

Verdict

The call

The clearest difference is in-app purchases: Free Climb at none against circloO's 1. Free Climb also leads on ads (none vs shown) and update cadence (fortnightly vs every 2 months). circloO's advantage is ratings volume (2.5K vs 1) and device support (3 vs 1). On price and rating there is nothing between them.
