Seems to be a great way to introduce kids to ttrpgs: with drawings, instructions to follow, and a story based on friendship. Nice idea!

Maybe after reworking the typeface or make the instructions more playful (by writing them on cards? same for the home by suggesting several "models" to bring diversity), it would become a great game and would make children want to play again many many times

I guess you forgot the "rescue" word here: "Tell the players and why they need to them." ?
