About Undertale 10th Anniversary

Geometry Arrow is a high-speed 2D precision platformer that tests your reflexes, timing, and control in a minimalist yet intense environment. You guide a constantly moving arrow through narrow paths filled with deadly obstacles, where every second demands full concentration.

The gameplay is simple in concept but incredibly challenging in execution. The arrow moves automatically at a fixed pace, and even the smallest mistake results in an instant restart. This creates a fast retry loop that keeps players engaged while pushing their skills to the limit.

With six progressively difficult levels, Geometry Arrow offers a pure skill-based experience that rewards patience, practice, and sharp reactions.

How to Play Geometry Arrow

Master the Diagonal Movement

The arrow continuously moves forward at a 45-degree angle. Understanding this constant motion is key to controlling your path through each level.

Control Vertical Direction

Hold the control to move diagonally upward and release to glide downward. Finding the right rhythm between holding and releasing is essential for precise navigation.

Avoid All Obstacles

Any collision with walls or objects will instantly end your run. Only the floor and ceiling are safe to touch, so use them strategically to stay alive.

Use the Full Space

Take advantage of the entire screen, including edges, to adjust your positioning and create more room for movement.

Progress Through Challenging Levels

Each level introduces tighter gaps and more complex patterns. As difficulty increases, you will need faster reactions and better control to survive.

Controls

• Click / Tap and hold – Move diagonally upward
• Release – Move diagonally downward
• Tap repeatedly – Fine-tune movement and maintain balance

Improve Through Practice

Success in Geometry Arrow comes from repetition and learning. Memorize level layouts, refine your timing, and gradually improve your performance.

Geometry Arrow delivers a focused and rewarding challenge where precision is everything. Stay calm, react quickly, and prove your skill by completing all six levels.
