Good game, but needs improvements

I want to start off by saying that in general, this is a good game. I like that it brings back familiar characters from my childhood and I love the fact that Im "building" my own Magic Kingdom.
Now, the reason I gave this three stars is for a few reasons.
First of all, notifications are basically useless. They wont notify me that a task is done until AFTER Ive already checked it, and on top of that, it will notify me for things that I had done days ago, like for example it told me that "Pizza Planet is up and running" I had already built Pizza Planet 2 weeks ago.
Secondly, I think the Happiness meter goes down way too fast. I understand that it has to go down to give players a chance to continue building wishes in order to bring it up, but its ridiculous that I could have 80% happy then go to bed and wake up for it to be 50%. I dont get enough wishes for it to stay up in "ecstatic" when the happiness goes down ridiculously fast.
Thirdly, gems. I think it should be easier to earn free gems like by watching videos. I really want Pluto or Rex, but I dont earn enough gems to buy either. I wish you would either lower the price of characters or help earn more gems. I dont have enough money to buy gems.
There is other issues with this game but these are my biggest concerns. If it werent for these I would totally give it 5/5 because overall its a good game it just needs improvements.
