circloO

originally, i started playing on the free version on mobile, and i liked the game, so i bought the steam version. this game is simple but pretty fun. i mostly play the game for the level editor due to how versatile it is, but i also enjoy playing custom levels. the updates are pretty often so it's a plus. overall i'd recommend this game, it's a pretty fun platformer with simplistic style.

Fun game but i would like comments on public levels and descriptions of the level and maybe public profiles

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. The expanding world design constantly changes how players interact with familiar spaces. Areas that initially function as solutions later become obstacles. Structures that once provided momentum may eventually require different approaches after the environment grows larger. This evolving design philosophy keeps stages feeling dynamic rather than static. Instead of simply introducing completely separate levels repeatedly, circloO encourages players to revisit and reinterpret spaces they already understand. Movement mechanics remain intentionally limited, and that simplicity becomes one of the game's greatest advantages. Players primarily move left and right while physics handles momentum and environmental interaction. There is no traditional jump button available to bypass challenges directly. Progress depends entirely on understanding movement, gravity, slopes, and timing. Every obstacle becomes a test of how well players understand the rules governing motion inside the environment. This design creates a surprisingly satisfying learning process. Early stages introduce concepts gradually before combining them into more demanding situations later. Physics interactions expand naturally throughout progression. Environmental features such as moving platforms, unusual structures, gravity manipulation, and momentum-focused obstacles create variety without abandoning the game's core identity. New ideas consistently build upon earlier mechanics rather than replacing them. One of the strongest qualities of circloO comes from how effectively it balances challenge and accessibility. Puzzle platformers sometimes become frustrating when difficulty spikes appear too aggressively, but circloO maintains progression carefully. More demanding sections require patience and experimentation without feeling unfair. Mistakes rarely create major setbacks because retries happen quickly. This approach encourages players to continue experimenting rather than becoming discouraged. The physics systems deserve particular praise because movement consistently feels reliable. Success comes from improving understanding rather than fighting unpredictable mechanics. Small adjustments in positioning or timing often create dramatically different outcomes, reinforcing the feeling that mastery develops naturally through practice. Solving difficult sections feels rewarding because progress depends on learning rather than luck. Minimalism shapes more than gameplay alone. The visual presentation adopts clean colors and simple environmental design that keeps focus entirely on movement and puzzle solving. There is very little visual clutter competing for attention. Every platform and obstacle remains easy to understand, which becomes increasingly important as levels grow larger and more complicated. The restrained artistic approach strengthens gameplay clarity while giving the game a distinct identity. Audio design complements the overall experience effectively. The soundtrack maintains a calm atmosphere that supports concentration without becoming distracting. Combined with smooth pacing and quick restarts, the presentation creates an experience that feels relaxing even when challenges become difficult. circloO rarely creates stress. Instead, it encourages patience and experimentation. Replay value receives a major boost through additional challenge stages and player-created content. Beyond its main progression path, the game includes more difficult content designed for players seeking mastery beyond standard completion. The inclusion of community level support significantly extends longevity as well. User-created challenges expand the experience far beyond official content while encouraging creativity among players. The focused design philosophy naturally creates some limitations. Players looking for larger stories, character progression systems, or gameplay variety outside physics puzzles may find the experience intentionally narrow. circloO commits heavily to one core concept and refines it rather than constantly introducing entirely new mechanics. Its relatively shorter primary completion time may also leave some players wanting additional official stages. However, the quality of design largely compensates for scale. The experience remains memorable because every mechanic feels purposeful rather than excessive. Despite its minimalist structure, circloO delivers impressive depth through intelligent level construction and strong understanding of physics-based gameplay. Florian van Strien demonstrates how creative design can create compelling experiences without relying on complexity or spectacle. The game consistently builds on its ideas while maintaining accessibility and challenge in equal measure. For players who enjoy puzzle platformers, momentum-focused gameplay, precision movement, and games built around mastering elegant systems rather than overwhelming mechanics, circloO offers a rewarding experience filled with clever ideas and satisfying progression. Its simple appearance hides a remarkably thoughtful design that continues finding new ways to surprise players long after its opening moments. Rating: 7/10

--> 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 game is minimalist but don't let that fool you. With three main sections of 28 main puzzles EACH and over 1,000 puzzles from level creators this game will keep you preoccupied for a VERY long time to come. Good luck. You'll need it.

great game

a game with circles

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.
