Thank you for fixing your image, @voiceless12. Your story is very interesting and suspenseful, though it has the feeling of being just a part of a story. We don't read the beginning which told of the protagonist's father. And the story does not resolve in the end with victory, or with Sam and Philip finding the crystal and making it through the tunnel.
We hope this feedback is helpful. With short stories, we look for a beginning, middle and end. Be sure to check out our catalog of fiction writing tips, referenced in the previous comment. Good luck and keep writing!
