To master the extended hyper dash in Celeste—a technique pivotal for achieving high-speed movement and optimizing gameplay—follow these structured steps:

Step-by-Step Guide to Execute an Extended Hyper Dash:

1. Crouch and Dash:
– Start by crouching. This is accomplished by holding down on the control stick or the corresponding key.
– Next, perform a diagonal downwards dash. Execute this by pressing the dash button (usually the shoulder button or a designated key) while simultaneously directing your movement left or right—depending on your intended direction. This action will send Madeline into the ground at a downward angle.

2. Wait Briefly:
– After completing the diagonal dash, it is crucial to pause for approximately 10 frames. This delay distinguishes the extended hyper dash from an instant hyper dash. Timing is essential here; a brief wait prepares Madeline for the next action and helps build momentum.

3. Jump After the Delay:
– Following the wait, press the jump button. This jump, executed after the slight pause, leverages the momentum gained from the crouch dash, resulting in Madeline launching horizontally further than with a standard dash or jump.

4. Dash Refund Mechanic:
– One of the key advantages of the extended hyper dash is the dash refund mechanic. By jumping at least 10 frames after the initial dash, you not only gain enhanced horizontal distance but also regain your dash ability. This refund is vital as it opens up further movement options midair, enabling additional dashes that can keep momentum going strongly.

Summary and Importance:
The extended hyper dash technique comprises crouching, executing a diagonal dash, pausing momentarily, and then jumping. This sequence achieves a significant horizontal speed boost, crucial for proficient movement, especially in speedrunning scenarios. The ability to refund your dash is equally important, as it allows for a fluid and continuous motion, which is essential for traversing the more challenging levels of Celeste.

Key Points Recap:
– Crouch and Down-Diagonal Dash: Begin with crouching and dashing into the ground diagonally.
– Wait ~10 Frames: Incorporate a deliberate delay post-dash.
– Jump for Extended Boost: Execute a jump following the delay to maximize horizontal distance and receive a dash refund.
– Utilize the Refunded Dash: Take advantage of the refunded dash to maintain speed and control in the air.

By perfecting the extended hyper dash, players can significantly enhance their gameplay efficiency and speed in Celeste, allowing them to tackle even the toughest challenges the game offers.
