Thanks for playing!
Quite hard indeed. I think in the latter part of the game, from my testings, the most effective strategy is to throw golems diagonally away as fast as possible; they are almost guaranteed to hit other golems behind XD
I am only very recently aware of the bug you mentioned... huh... if I have to guess perhaps it's due to the smaller "clickbox" that I made for the golems...? Thanks for the feedback (^_^;
