First of, I just want to lead up with saying that I know there are already two guides for this achievement by two people who both figured out this same method. Their guides are both nice and detailed, so I'm not trying to undermine them.

I just figured I'd post this here as well since I'd already made the video, and maybe some poor soul out there prefers to watch a video of someone explaining, and proceeding to do, the achievement.

If you can't be bothered to watch all the nonsense, it boils down to using the keyboard and mouse controls rather than a gamepad, binding the dash key to something you're comfortable with (LMB for me) and just clicking one spot on the ground over and over. I found out after the fact that the purple tiles on the ground actually recharge your dash meter. So make sure you're dashing across one of them over and over.

I'd recommend muting the game audio as the delayed dash sound might throw you off. Beyond that, just stay calm and don't worry too much, the window for chaining is quite lenient, as you can hear by the fluctuations in my dashes.

I only found out after having played the entire game, but as it turns out, the different outfits you can find around the world actually have some helpful effects and aren't purely cosmetic.

There is one set that you get in the West section once you've found all 8 modules and completed the dash challenge south of the warp pad. The set looks like this:







It isn't completely confirmed what the set does, but some believe it very slightly improves the window in which you can chain dashes. You only need to equip one of the three pieces, using more does not increase the effect. It might be placebo, but it might also be worth the shot if you're struggling.

To get the set you have to dash through narrow corridors across a complete floor of crystal spikes, and it can be very challenging. I have one piece of advice to make it easier. Dash three times, then BONK! into a wall. During your bonk animation you are completely invulnerable to spikes that have already been activated. So you only have to dash thrice, bonk, get up, dash thrice, bonk. Rinse and repeat. Be prepared for a messy fight at the end of the challenge. I recommend bringing bombs and having the [A + X] dash attack to make it easier.
