Intelligent Qube problem / question

[bobbye]

I am playing Intelligent Qube , this is a great
game, but I have one problem - I still did not reach the final level,
and I can't seem to save the game in between the levels.
Everytime I need to start from level1 and this is realy anoying.
The save option is only in the options screen and not after I complete each level.

Do you know if I need to finish all the levels in order to save the game (it doesn't seem logical, but I read somewhere that after finishing all the levels I can save the game and create my own puzzels).

Thanks

Bobby
