Yea, you can destroy parts with right-click. You have 5 bombs for that, but destroying multiple blocks can make things even more complicated as you can only move blocks that have one possible direction :D I was hoping this could be an interesting mechanic, but didn't have time to put the finishing touches on it. The best strategy is probably just to clear one piece, solve the puzzle normally, and then use the remaining bombs to solve it only at the end.
