Cant belive i'd say this, but...
i think this Ludum Dare i'll take the obvious route for the theme and gonna make a (food-)delivery based game. Normally i try to go a littlebit exotic with the theme, but i got an idea for a game already and i really like it :3 Also, last Ludum Dare i wastet A LOT of time on getting any idea, so i'm quite happy to have something already this time :D
Good Luck for all of you still looking for an idea - something that came to mind as soon as i saw the topic, "child delivery", maybe this helps someone :3
