The whole thing felt pretty short. The pacing was a lot quicker in this one, but really that was a good thing overall. The original was pretty slow. I think there was room to flesh things out a bit more. You know, add a few more stops on his trip. Show him getting hungry and looking for food, then devouring the pie. I'm especially disappointed that you left out the actual explosion at the end!
Still, it was a huge improvement. The backgrounds looks fantastic! The music along with the backgrounds gave it a nice relaxing, tropical feel. Very pleasant. The animation was smooth, although there was room for more of it (like eating/exploding).
Like I said. Big improvement, but there was room to expand on the original. I feel like you restrained yourself to the same plot beat-by-beat.
Maybe I should remake something of my own someday?
