Love it
I love this game! Some puzzles are really challenging. I don't think I've seen this exact type of puzzle ever before. It's also fun that some monster sounds are more rare than others.
I got a medal saying that "somehow" I was able to solve a puzzle in fewer than star moves :D I did it by using the R key and then really quick mouse action to drag a monster falling down to the right with a white block, in a way apparently not predicted by the designer of the original levels :D
