circloO

You can see my playtime... Absolutely formidable physics-based platformer puzzle game. The set levels are good and lead to interesting challenges but the user-made levels just shake everything up! How do people make that kind of stuff with the level editor? Look through the playlists, it's really good.

circloO is a physics-driven puzzle platformer developed and published by Florian van Strien that proves how a simple idea can evolve into something remarkably creative through strong execution and thoughtful design. Built around momentum, environmental interaction, and constantly changing level layouts, the game takes a minimalist concept and transforms it into an experience that feels surprisingly deep without becoming complicated. Instead of overwhelming players with combat systems, skill trees, or narrative-heavy progression, circloO focuses entirely on movement and problem-solving, creating a gameplay loop that rewards experimentation and precision. At its core, the game places players in control of a small ball navigating circular environments filled with obstacles, slopes, moving objects, and physics-based challenges. The objective initially appears straightforward: collect circles to progress. However, each collected objective causes the level itself to expand outward, preserving everything already present while introducing entirely new areas around it. This single mechanic becomes the foundation for nearly every puzzle and creates one of the game's most memorable strengths…

Very underrated, deserves more attention.

--> This game runs in Manjaro Linux without proton or wine! <-- If you relish keeping your fingers from some massive cramping and arthritis, this game is NOT for you. Bar none, I'm just telling you this if you have serious problems using a keyboard for movement. The game is fun but at times you'll curse at it for some of the most ludicrous moves you can ever pull off in a simple game that requires you to move a ball or marble. For the first 28 levels it took me 83 minutes. Not a joke and I KNEW I placed that ball at just the right place but the game refused to let me have the next step. The anger, cursing and downright evil that incorporates your mind is just the beginning as you play each level. The physics in this game are no joke and you'll learn this quite quickly. Depending on how many places you have to touch with the ball, you can wildly go bonkers across the area very fast. You'll have to do your best to move right and left to manipulate the ball to do something else. There isn't much else to the game but moving back and forth but each level contains some wicked puzzles and these puzzles will wrack your mind. Overall the game looks simple but it's far from it. Yes the g…

What I liked: -unique concept -relaxing music -for the most part, actually well playtested and fair levels What I disliked: -the levels that were clearly not playtested or just specifically designed to by as annoying as possible -the stupid achievements My verdict is negative because when this game gets bad it gets REALLY BAD. The fact that you only use 2 buttons to move in this game makes you feel so helpless when it requires you to go back and forth just to get 1 milimeter higher or to somehow get over all those circular obstacles. Like 80% of this game is quite good, but the remaining 20% is just so horrendous that it ruined my opinion on the entire thing.

great game
