Causality comes from Loju and was featured prominently by the App Store Editors.
The object is to get the astronauts to their portals.
* They mustn't bump into each other.
* Arrows must be rotated.
* There's a limited # of moves.
* Portals

What's most interesting is that there's a time-travel component.
There's a clunky element that's a bit annoying: every step of the journey must be swiped singly.
I can see people really getting into this game. But I'm not feeling it.

I've solved about 15 of the 60 levels.

Lojo made another game Transmission which I reviewed about 2 years ago.
