Not an expensive product, so I decided to see whether my 9-year old daughter may deserve it. Downloaded using an intel mac, tested, works, stopped after several seconds asking for buying it. well, well, just several seconds to decide?
Moved to an older 12 in Powerbook, runs beautifully, again asks for buying it after several seconds.
So, believe me, it is impossible to decide whether to buy or not after only 5-10 seconds, could not realize whether appropriate or not for my daughter.
The author should be merciful with parents, really cannot dedice whether appropriate or not for my daughter and, if so, whether she deserves it. Several seconds are not enough. Looks good and serious, but who knows?
