My only guarantee is that all levels in Bulldozer and Duck Tiles can be beaten.
Sir, I regret to say that your reply is not helpful. Kindly show me how you can solve levels 79 and 111, where there is no possibility of establishing a galley for the bulldozer to move around in. I am sorry if I have overstepped the liberty you have given to your clients and admirers. Publishing the pass keys for all the levels will help youngsters whose morale may be hurt by failures. With my sincerest wishes and warmest regards.
