Finally yesterday i have try again the level with the truck. A friend take the pad of my daughter and die quickly lol
I have take time to pass this stage and finished your DEMO
- But this stage is really hard, we must found the good movement to do at the exact second, we can't do any error !!!
-- It is impossible to release for a little 5 years old girl
-- I think it is also impossible to release with two players because if one day the two are dying

Maybe you can let the other continue alone ...
- When my friend is dying it is the first player, i'm the second, and when there are dialog on screen only the first player can interact with them ... it's not really cool, if the other players can too, i think it will be better.
Sorry for my bad english

Thanks for all
