Amazing what one can do with a simple, elegant mechanic and a creative idea. I loved the game. Sometimes I would appreciate highlighting which EXACT tiles will be placed, while hovering on the right side.
When you stare at it long enough, it gives you the scintillating grid illusion, which is kind of interesting.
And please tell what am I missing here, because I am at my wit's end. O_O
The devil is indeed in the details.
