I'm happy you figured it out!
The game is about overcoming difficult adventuring puzzles. The reward is seeing the puzzle become solved after being stuck on it for a while. For that reason, I couldn't give any hints, because that would go against the spirit of the game. It's all about the puzzles.
Thank you for persevering!
