Room C5 "Jailbreak"

Think about force-field mechanics you've learned so far. Your existing knowledge should get you through this puzzle.

Free the particle from its initial prison first of all.

Push a right-arrow into the leftmost force-field to do it.

You'll have time to think whilst the particle bounces back and forth.

Think carefully about the order to activate the receivers.

You'll need to bounce a particle off a force-field to activate one of the receivers, so do that before disabling the force-field.

Activate the top receiver first.

There's only one order you can activate the rest at this point.

Turn off the horizontal force-field, then activate the receiver below it. Finally, use a right-arrow in the right-hand force-field along with the down arrow to activate the last receiver.
