Really cool game! I personally would also make vertical whole bars count because that'd make for a more dynamic game maybe?

We had a version where you could do vertical and horizontal. Our early mockup even had that feature.
But when testing I felt it was better for the player to focus only on the horizontal. That helped with balancing the difficulty and it also avoided to clear the board unexpectedly. With only horizontal it is a bit more focused.
It is possible to balance the game to work both way. We just ended up using only lines.
