Like the hand-drawn art of your game! Also love the Flying Castle setting (I am a huge fan of Miyazaki - his films, of cause, but especially his masteful art style - his work is one of my biggest inspirations).
But I am not very good with solving the puzzles. Do you have a walk-through somewhere, or at least a first-steps tutorial? In the first puzzle, I thought to reach the swtich/lever, I have to disassemble myself and fall throught the open gap in the ground. But it doesn't work, so I am stuck at the very beginning already. Don't want to rate your game in this situation, so help would be appriciated.
Also made the art for a game called "Roboto" in the past (https://orolock.itch.io/roboto). Completely different setting, but the goal is also to escape the place successfully.
