! SPOILER WARNING !
I saw the six fingered journal and was like, "HAH! I get that reference!" and then I saw the hat and was like, "Oh wait- the whole thing is a reference." This is a neat little game. Great job!
The slide puzzle controls confused me. I tried to slide them with my pointer but only moved the selected tile when I clicked. I thought it was broken at first. You should be able to control which block slides by clicking it. Also I think it was too easy. Also when you placed the missing tile there was no feedback telling me the win button opened.
Key looked like a car key so I tried to use it on the crashed truck, which obviously didn't do anything. Not sure how to change that though.
The wave puzzle was more of a guessing game than a puzzle. Because it had numbers I assumed there'd be a piece of paper with values or something. I thought I was being pretty cheaty when I guessed it.
The Simon Says kinda threw me for a minute. I was expecting a memory minigame, not a color lock.
Good job having more than one object float- I missed the box so I got the table.
I loved the art. It was very cute. Slight problem with the hat though: It puts a hole in the character's head. It's kind of terrifying.
