I really love what you did with the Crooked Man (both how you changed the nursery rhyme to fit the urban legend angle, as well as how you made the character your own.)
The premise of the player character going to search for this possibly non-existent urban legend and actually coming across him was a lot of fun. I also loved that magic and wizards are a thing in this world, and that the Crooked Man's magic centres around candy. Which makes sense, since he does exist within a candy shoppe.
But the candy magic/candy itself was a hell of a fun way to get the different endings. It honestly made me laugh that every choice save for the "right" one gave the player character fairly terrible outcomes. The fact that the Crooked Man is just so underlyingly antagonistic is brilliant.
(Though I'm still not sure what he saw in the player character that made him want to teach them in the good ending, but it was honestly a nice turn with his otherwise terrible personality.)
I really loved the Crooked Man as a character too.
His design is positively gorgeous (and yes, I do have an adoration for sharp teeth...), and his behavior made me laugh in spite of the fact that he was pretty awful.
You really did a great job with this whole story and I think you set everything up very well. It felt very polished for a game jam game!
I look forward to seeing what other games you come up with! (and I hope the Crooked Man will be in some more of them!)
