Math Planet - Fun math game curriculum for kids

My five-year-old really really likes this game. He plays it almost every day and it is a great way for him to improve his math skills. However when we reached planet five the game continuously crashed. We haven't been able to even open one of the levels because it keeps crashing. This really upsets me because this game wasn't cheap. If Playpower doesn't do something to fix this I'm going to call Apple and ask for my money back. So dissappointing.

My kids love to play this and it's such a great way for them to sharpen their math skills, but..... it crashes! Once my son got to a certain level he couldn't go any further. Crashes every time. I payed way too much for this kind of poor quality. I even wrote to the company asking if they could fix the glitch or give my money back but they didn't respond.

It's ok I just wish there were more challenging levels then what they are.
