Experience Physics Like Never Before with circloO

circloO by Florian van Strien takes platforming to a new level by ingeniously merging creativity with real-world physics, offering a unique gameplay experience that challenges players' problem-solving skills.
circloO is a vibrant physics-based platformer that revolves around a unique circular gameplay mechanic. This comprehensive version encapsulates every level from both circloO and its sequel, circloO 2, in addition to introducing a selection of new bonus levels. Notably, the game features a level editor crafted by the community, boasting over 1500 user-generated levels.
The player's primary objective is to navigate a small sphere through intricately designed circular landscapes, collecting circles to expand the playable area. As the circle enlarges, players must adapt their strategies to utilize and avoid obstacles that evolve with each expansion. For instance, platforms that initially serve as helpful aids may become formidable challenges as the level progresses.
Movement is restricted to left and right, necessitating strategic use of the environment to execute jumps and attain height. Players will encounter various physics phenomena, including shifting gravity, clusters of small blocks, elaborate contraptions, and even gravitational fields from planets. In particularly demanding sections, the gameplay fosters deep engagement, encouraging players to exert themselves in pursuit of collecting the next circle. Fortunately, failing a level never necessitates starting from scratch, allowing for rapid retries and an exhilarating sense of achievement upon success.
Key features of circloO Complete include:
- Diverse physics interactions such as ropes, pulleys, and changing gravity mechanics.
- A total of 53 increasingly challenging levels, including six "Hard Mode" challenges that test the limits of players’ skills.
- Inclusion of all levels from circloO 2 and the original circloO alongside twelve new levels.
- Unique physics puzzles in each stage to enhance gameplay experience.
- High-quality music and sound effects composed by Stijn Cappetijn.
- A minimalist yet colorful art style.
- Estimated completion time of two to three hours for most players, with saved level times for those wishing to beat their previous scores or engage in speedruns.
- A built-in level editor for community creativity.
- A blend of relaxing yet challenging physics puzzle platforming.
It is worth noting that circloO 2 was recognized as the winner of the inaugural Crazy Games developer contest among 200 participants and secured third place in the Kongregate contest held in November 2018. Fans may also recognize it from CoolMath Games.
