Hey all! I found this website http:/​/​ruwix.​com/​online-puzzle-simulators/​sliding-15-puzzle/​

And here's a picture of the clock:

I really liked it because
1. You can upload a picture of the clock and
2. Use the arrow keys to move the tiles similar to Mickey's Ultimate Challenge.

But maybe it's only 4x4 block puzzles so I guess that limits the use to Medium difficulty, even though general skill in solving block puzzles is good for speedrunning this game.

Hey thank you for the link, will check it out. I had the clock printed a few times and cut different sizes; but the feeling is different of course

Oh wow what a cool strategy for learning.

Ye this feels quite similar to playing the game. One thing though is that there is an animation when you move a tile, in the game it's instant. A funny glitch on the website is that you can actually flip tiles if you move too quickly, making the puzzle unsolvable. So that's something to be careful about!

I found a good browser website for practicing the HARD clock puzzle!

The downside is that it doesn't seem to allow arrowkeys for moving the tiles.
So if you can use save states that'd be a lot better, but still, this has its uses.
