circloO XL is a clever physics platformer where the level itself grows as you play. You control a small ball trapped inside a larger circular arena, using only left and right to roll and build momentum. Every time you touch a target circle, the outer boundary expands, revealing new platforms, ramps, and gravity-defying loops to navigate.
The challenge comes from mastering the ball's momentum. Instead of jumping, you have to swing back and forth on curved surfaces to gain the speed needed to reach higher areas. Each expansion of the circle completely changes the layout, forcing you to rethink your route using the new terrain.
Controls
- Move left: Left arrow key, A, or tap the left side of the screen
- Move right: Right arrow key, D, or tap the right side of the screen
Tips that actually help
- Use the bowl shape: If you cannot reach a high target, rock back and forth in a curved area to build up speed.
- Don't hold a direction constantly: Sometimes you need to let gravity pull you back down perfectly before accelerating up the other side.
- Momentum carries over: When the circle expands, you keep your current speed. Try to hit the target circle while moving quickly into an open area.
