What can I say other than the game is absolutely perfect. I love everything about it. The design is out of this world. The puzzles are just the right difficulty to take a while to solve but eventually, it will be solved. I would be interested to see if there are more mechanics that could be brought in with a 3D space hmmmm (Lemme know if you are interested ;) )
If this was an app, id be on this all day, swipe to move, id lose so many hours.
I have not beaten it yet, but i will, oh I will. Just you wait!
