Arbitrary game with unrelated, unfinished story

Game is unfinished. I only care about the story because the gameplay is finicky yet insulting easy. But when I get past level 5, it unceremoniously has no more levels. I paid for this, so give me a complete game. Finish the story. Why is this released unfinished? How is gravity drop related to the story? Boo.
