Description
3 separate rooms, 3 separate cubes, and 3 separate switches. Seems simple enough, right? Well, these rooms are a little bit more intertwined then you think. You may even have to get some cubes more than once.

And remember, as with all permutuations, Order Matters! Let the light guide you if you're not sure where to go next.

Difficulty: Medium to Hard

Solved it in 3-4 minutes. Also the first time I ever played the Perpetual Testing, tried to make a map a few year ago but never played any. I'd say this was a easy one, but maybe that's just me.
