My Life Became A Game Before I Knew It!

This is my first story and I'm not sure where I'm gonna go with it yet, just had an idea and wanted to run with it, hope you enjoy. (will likely not that update often, not based on anything in particular)
Plot Synopsis:
(Long version, there is a much shorter, "here's the gist of it kind of synopsis below if you jus want the key points)
This is a story of a guy named Henry Reese Sampson, relatively average in every way, with a hint of introversy to boot. He knows the fine line to stay in to avoid getting in trouble with others, but due to this tends to keep people at arm's length, never really letting anyone get too close.
On the day right after his high school graduation, Henry was running an errand downtown. Everything seemed fine until a kid ran the street to try and get his baseball right when a truck was approaching. Lucky for the kid, the truck was able to veer away to save him, but Henry wasn't as lucky because the sudden stop caused the car behind it to go off the street and crash into Henry.
As Henry's life was flashing before his eyes he finds himself in a black void with nothing except what appears to be a screen with numbers counting down from 90. Confused and with nothing better to do, Henry waits as the timer counts down to zero. When 90 seconds had finally gone by, Henry gets engulfed in a ray of blinding light, before waking up in his room moments later. This is where his story truly begins.
(Slimmed Down Version)
Main protagonist Henry - average, few friends, no real close friends, weaves by socially (you know general protagonist/reader insert character stuff)- dies, revives, powers, secret hidden world, like I said: the gist of it.

*Author's Note* Open to advice and constructive criticism, which I may or may not take. (maybe I'll fit some friendship and romance subplots in there if I can work something out)
And about the title, honestly just made up a word that I thought sounded fun, will work on it.
