There's a glitch where the fade out transition restarts if you click the button again. So you can click an arrow or a person or the final line of dialogue over and over and it'll just keep fading and fading. I presume it's in your other games as well if you just reuse the same code.
I'm stuck at the sword garden. I have the wood and the locket. Have tried every item on everything including each other and people. Then I tried random click throughs of every room with every item. No dice. And yes, I've tried scanning the junk in every room to see if the hand changes. Haven't found anything. What room should I look in? What am I looking for? A musket ball? Those things are tiny.
For those stuck on the first puzzle, it's easier than you think. The path on the right literally tells you exactly what to do. For each horizontal line, put gaps where the path on the right would pass through them.
