Fun and challenging game! I don't understand why certain solutions aren't valid, like this one, but I'll assume it's because all pieces need to be used.

I just finished the last level, this game is so good! I love the way it broke my brain a little :) congratulations!

Thank you for pointing that out. The level's progress does indeed require the use of every bridge, but this wasn't the level I intended. I've now modified it.
