This isn't even a game.
Lemme just tell you something. I've played bad games before. Not exactly awful, but still bad. But I still except them for what they are, because they are still playable and somewhat enjoyable. THIS, however, is probably the WORST game I've ever played. I wouldn't exaggerate the term, but it indeed is the worst I've played yet.
Story: Guy has nightmare, guy has to escape, etc. Not much to say here except for... WHO THE HECK IS RED?! Couldn't you give us a little backstory? In most games, you actually know who you're playing as, and you know what that character is like and so on. Here, you just go like: " Here's your player, have fun." You left the train dead on the tracks with nowhere to go.
Character and enemy movement: Glitched up. I'm just walking through the level, looking for more enemies to shoot, when I stumble upon an enemy moving THROUGH THE GROUND. With the character movement, I'm mainly just wondering why he doesn't have any legs. Does he have wheels in his DNA or what?
CONTROLS: Holy crap, these are awful. Let's list the flaws in this:
1: The jump length is random; it NEVER stays at the same length.
2: You only get on the ledges with pure luck. I was spending 30 seconds trying to get on ONE LONE LEDGE.
3: You say you can climb stuff in the game, but for most of the game, there are NO spaces where you can climb.
OVERALL: Crap. Garbage. An abomination. The worst excuse any game I've ever played. As much as I hate to break it to you, you should REALLY practice on making games. To be honest with you, I didn't like to go all AVGN on you, but it's my honest opinion. I don't care if someone flat out ADORES this game, it's getting my opinion out that I feel is best. Sorry if you might not like this review, I honestly didn't like making it. I don't normally get really angry because of a flash on Newgrounds.
