In the game Breathedge, your movement speed in space is quite slow - this chapter will help you build an accelerator that allows you to increase your character's flight speed.
During Chapter 1 of Breathedge, once you exit the capsule, look to your right. Head towards the section marked with a (1) in the screenshot above. Next to the toilet, you'll find a floating Shawarma. It's one of the accelerator's components and collecting it will unlock a new blueprint.
Now head to point no. (2). This is where you'll find the second toilet. It is surrounded by floating yellow spheres - collect one. This is the yellowish water, another component of the accelerator. You will now learn its blueprint (4 pieces of ice).
Then, return to the pod and create the accelerator, adding refined metal to both components. To use it, press the acceleration key (Shift by default). The resulting speed boost isn't significant and only increases your flight speed for a short while, until it regenerates.
