One of those 'invest steps early, save more later' type of tricks. Nice design! Sometimes you've just got to push through the weak spot instead of making a weak spot in a wall. 3 possible "tricks" and of course that was the last one I tried! Again big fun. I love that type of levels. I applied one of the famous tricks for those types of boards here, that worked immediately so that I needed just one more try for optimization. sure had ME in a loopty-loop
