Sadly i couldn't get pass the first level lol but looks fun, it does give the feeling of these escape puzzly games, good job to both of you for your first jam!
The hint to the puzzle is in the right room and it has to do with the painting in the middle room, each color represents a number. The X next to the green color algo represents the 'amount' of that color in the painting. Hope you can retry the puzzle!
If the timer runs out the son will catch you and you'll get ending 0, but if you complete the puzzles in time you'll get a different ending depending on what you did with the ring and the bear!
