I enjoyed the puzzles, I definitely got lost a couple times but it was fun. Cool to see you made the game with your nine-year-old brother, I would've loved to do a project like this at that age.
Happy to hear you got un-lost! :) What would you say were your favourite or most difficult parts?
I hope to do another project with my brother now that he's ten. It was a good experience for us, I would definitely recommend finding some project where you can work with someone much older or much younger than you.
