Thanks!!!
I am a little confused by the chain tile suggestion, because it does have an indicator.
It actives in a line (both sides) from the direction you came from.
Which is indicated by unique indicator "lights".
Ohhhh it's from the direction you came from, I though it just rotated it's direction every move you made.
I think it's still not very clear how it works though, I didn't get it throughout my entire playthrough.
I love the chain tile itself though, Lends itself to alot of cool puzzles.
