so my son is really liking this, but i cant seem to save progress in the mini games?

i.e andys house where you you have to retrieve house phone and andy's mobile phone, he does the first part then onto the second part, at this point he gives up (hes only 4!), so i save it for him, (start>save), exit.

then when I turn it on again, he has to start from the beginning of the level! very annoying!

is it possible?
