nice game , i will show it to my children . i didn't understand the free play .. challenge is good , maybe a bit too long . come to try my game sonotone ( it's musical and educational ) .
Free play was just for interaction, so you can discuss the clock with your child. Then they can try the challenge and play it until they are bored :) Then they can move to the Clock Quest game for more challenges. Thanks for the observation, I'll think how to make it more clear.
Love it! Gonna test on my daughter. I also got confused with free play. Maybe a menu where you select "Free Play" or "Challenge " in the beginning would help?
