The beginning is fun and really well done, but these types of stories usually fall off hard once the main story begins.
I can only watch the protagonist be amazing at everything and have his cheerleaders praise him so much before it gets boring. The author needs to introduce something good for the story to have legs and stick around. Maybe flesh out the world or characters. Maybe get more into the building of relationships. It gets stale if the characters, world, and other story details lack substance.
