I think you've got the curve pretty right. I've not played this style of game much so I was overwhelmed at the beginning with everything I was supposed to look after, then finding where those things were, then understanding how they were represented on the GUI... but after getting all that it's fun to play through.
Sometimes I make a mistake and get the baby stuck in the bin! (and couldn't figure out how to restart).
I'll definitely come back and try to finish the game. :)
