Only one problem – Middle School Math Planet - Fun math game curriculum for kids Review

My kids love this, even the ones I thought would be too young for it. My only beef with it is that it gives me a black screen of death on the last level of the 5th planet. If this could get fixed, it would totally get a full 5 star rating. This is probably my kids favorite math app.
