TryCat / Wordle code

I recently stumbled upon the TryCat / Wordle Workshop video series and really, really like the end result.

I run a free, educational webpage for Norwegian children aged 5-12, and I'd love to add it (or something similar) to the page, as a fun way for children to practice their English skills.

Am I allowed to use and/or modify the code shared in the series on my webpage, i.e. Mypage.com/trycat?
