The hitboxes are a bit wonky when the witch attacks. I suggest having 2 hitboxes for each statue, the one you already have for pushing the statue around and a bigger one that only collides with the laser beam that the witch shoots. That way you'll have less situations where the player dies while standing between 2 statues or hiding behind the edge of a statue.
I like this game and its puzzles. It took me 32 girls to beat.
