Level 25

Hi I like this game as it has a variety of challenges. However, Level 25 is not solvable so I cannot get any farther. I have gone to the developers but they seem unresponsive and their forum is closed. There are not enough puzzle pieces to fit into the shape. With every available piece in the correct place, there is a gap where another triangle should be but there is no second piece given. It is definitely a dud! Too bad as i would have purchased this game. Anyone tired this game this far?
