Very good. My only critique is I’d like hints to what happened and how he got there in his monologue. But his monologue is still great, tough call with limited space.

“Inch by inch towards to pier” should, I assume, be “towards the pier” but other than that, agreed, it was a damn solid piece of fiction- nice imagery with the incoming shots.

Good writing and dialog. Only complaint (besides the edit that edcrab mentioned) was that it was a “wall of words”, which made it a little difficult to read. A line space when he starts his dialog would have helped.
Also, the phrase “you stupid fuck” is more commanly used than “you stupid fuck-up”.

Thanks for the comments, I’ll fix the formatting and typos presently. “Fuck-up” is also just my personal choice for self-deprecating language as it more intones the sense that you’ve ruined things and aren’t simply a very confusing nounization of a verb.

Why the fuck can’t I put in blank lines?!?
