There should be a confirmation page before moving onto the next progen. Like, “This is how your first wolf is going to look like. Are you sure this is the wolf you want?” And then show the wolf and traits before moving onto the next. Without the confirmation screen, it's easy to accidentally move through it too fast and you could end up with a wolf you don't want.
I was hitting too fast with my first progen and now he's a Lupin when I wanted him to be a Kit. Sure it's an “easy” fix if I have the currency, but it doesn't change the fact that a small error like this is very, very costly.
