I think you are spot on with all your comments and really good. There is a lot of polish lacking and I would like to do much more but it's all very time consuming and between family and daytime work on a AAA-game, it's been difficult :)
It's interesting because a game like this really triggers your imagination and there is so much you can do! More wildlife, more dialogues depending on lead character and timing, more interactions such at looking at toys in the kid's room, mini games such as video games or arcades, deeper puzzles, gadgets etc.
I think the main struggle is graphics to be honest, it takes forever!
Thanks for taking your time to play through the demo!
