What a wonderful game! I tried this game when it first came out, but it was too hard for me back then. Now it is still as difficult as I remember, but I prevailed, and it only took me a week to chip away at the puzzles! Completing this game and Alephant are two of the most significant achievements of my puzzling journey, and I won't forget them any time soon.
Sorry about the deleted post, that was me asking for a hint for a level that made me stuck for 2 days straight, I have solved it since.
