Thank you for the kind comment!
Regarding level 44, I just tried it to see what the solution was and I have to admit that it gave me lots of trouble too. And I made that level! I'm glad you enjoyed the game, and I would like to give you a hint on how to solve level 44: try to create a tripod with the blue stars from the left side of the screen.
I made a quick Imgur video to show you what I mean. Hope it helps!
Next game I make I will be more careful with how I design the puzzles/levels.
PS: yes, pendulums! :)
