over a billion times

“Too many times” would suffice here. It echoes the sense of hopelessness your preceding sentences convey.

Each building has had its name removed throughout the years…….. ‘Tommy’s Burgers,’

“The names of the buildings have been removed over the years…….. Tommy’s Burgers”
“Along” should probably be “through” when you’re referring to Tommy walking up the sidewalk. If he’s walking in the street then it is fine. You can also take out “snow” when describing his eyes seeing that you’ve already described them as “Icy”.

he throws his head back and lets out a loud snarl. “Stop that!” I yell. I hear nothing but that hideous laughter.

I thought this was rather interesting. Not only is this child a ghost but perhaps a schizophrenic one at that. I can’t help but wonder how he died.
When you refer to the “river” after this add in “people” again so as to avoid any confusion it might cause.

In my palm a wooden stick dances……

This was a bit distracting. Just say that “I used a stick to construct an array…etc”

instead a pack of ice burns its way into my chest

“as an icy feeling burns into my chest” I think this will make it sound a bit smoother.
You also don’t have to say that he turned his “neck” to watch them or that they leave “behind me”. You can get rid of neck and say leave “me behind”. You can also join the two portions describing the couple leaving and the image blurring. Otherwise it makes it seem as if they passed through Tommy, he turned to watch them leave, and then fell to the ground afterward. If you were trying to convey that it wasn’t their passing that knocked him over, but rather he fell down on his own then the spacing is fine.
Overall I thought this was a pretty interesting piece. I think you were hinting that Tommy’s death occurred when he fell off of the swing set, but that portion is a bit confusing. There were also a few punctuation and spacing issues, but you probably don’t need my help with that if you read back through it. Strong work, hope this helps you,
