Good idea! There is definitely some work we could do to tell the player a bit better what was possible in the level design. Thanks for giving it a go :D.
If you're interested in trying to get further, I've put some hints below:
If it was the slime, what mechanic do you think you could use to kill it?
If it was the level shown in the screenshot in the entry, did you try throwing the hat again after the first recall?
If it was the snail, the wizard should pass down the left while the hat passes down the right.
