SHORT but costs $2+??

So I absolutely loved the graphics, animation, and music. But I finished the entire game in a span of 24 hours. I was sort of confused that it just abruptly ended, considering there is no free version. If there are more levels being developed, great, but this game shouldnt cost $$$ for such short game play. Or lower the price. Outside of the challenging puzzles and nice gameplay, there is no value to the amount spent.
