Ratings and Reviews
This is a cute game, but not suitable for children with special needs or children with slower reflexes. It's frustrating not being able to hit the answers, even at the lowest speed. It would work better if the turtles/answers could be stationary & the student move the octopus over the right answer.
With Family Sharing set up, up to six family members can use this app.
