Gridmancer. Is it real to see "comleted" at the level?

I played Gridmancer level and finished this level with 29 rectangles. But level is not completed. Is it nolmal? Can anyone finish this level?

It was designed as a challenge level to get the minimum number of rectangles so it’s open ended and it won’t “complete” per se.

That being said 29 is the minimum number so gratz ^.^
