Deeper character developement is better I think.
Choices are good, but if you don’t grip the leash, you won’t have time for the completely different story lines. Best experiences come when you did a choice, and you believe that choice has its result. For example the protagonist’s friend is going to fall down in the river. You can choose if you try to find a solution or just run to them. If you choose thinking, they lose their grip and fall down. If you run to help, the protagonist’s boots kick dirt to the friend’s face they lose their grip and fall down. This seems to be the same ending however… they will survive it and they will have different seeing about the case. If the protagonist stopped to think they will blame them for not helping. If the protagonist ran to them, they will blame them for the clumsiness. However if they are real close together, they will forgive quickly. These tricks can color your story without making completely new lines. Got it? :D You can use choices what seems to have no reason. For example you hide a gun in your desk. After a long time Emma is in danger in her room and she tries to flee, but you open her desk and there is the gun.
Animations are cute. I like them.
Interaction make the story more personal.
This is Emma’s story not mine. :)
