My feedback hasn't changed much from the last time you submitted this.
You have added more mouse-maze gameplay at the end. But it does take quite a while to get to it. You still have to sit through a lot of "next, next, next" in the beginning. It would be more interesting if the player had some control over what actually happens.
You've got a strong theme and story to work from. I would suggest cutting back on some of the boring parts, and focus on the interactive gameplay elements. Give the player meaningful choices to make, and more challenging tasks to complete.
