Room C2 "Recycler"

Make sure you know how the factory works.

It configures arrows to point in the direction you push them.

Most of the arrows in this room can't be moved but can be made use of in other ways.

Can you get a particle onto any of the unmovable arrows?

No? Try using the factory to configure the blank arrow to point left. You should be able to get a particle onto the fixed arrows now.

If not, don't move the arrow from the factory once it's pointing left. Then fire the particle.

A particle should now be revolving around the inner room. Can you redirect it to one of the receivers?

You might need to configure the moveable arrow to point in a different direction first.

Can you activate the other receiver in a similar way?

Have you used the outer ring of arrows yet?

Get a particle onto the inner ring of arrows, then redirect it upwards to the outer ring.

Point the arrow right, then push it in front of the remaining receiver.
