multicoredump/winter-wonderland ? reverse-engineered prompt

Build me a fun winter themed browser game for 4th graders where Frosty the Snowman is trapped in an ice castle and the player has to help him escape.

I want 10 levels total, with each level having a little hidden object challenge first, then a multiple choice or simple answer question from math or English. Mix in things like multiplication, fractions, area, vocabulary, synonyms, antonyms, and plurals. The player should only get 3 mistakes for the whole game, and there should be a clear progress tracker so it feels like Frosty is climbing higher in the castle after every correct answer.

Make it feel magical and playful with snowy animation, a winter background, cheerful sound effects, and a victory scene at the end where Frosty rides away on a reindeer sleigh. Keep it as a single page game that opens in a browser, and if you need anything current from the web, look it up online.
