Yep. There's an Option Menu besides or to the left where says "GAMMA BROS" and you can set the difficulties. I'm not really pointing out "the obvious", it's difficult to see when there's the sunlight shone on your monitor.
This game needs a separate page that confirms the Player's age or acceptance/refusals of discretion to let them in or not (some people don't read tags, and game instructions/no chance to, when the game is on the front page, rated high and all). It could give someone a heart attack.
You are a player, we are the players, we are the ones to find that out by playing a game. If it was all foretold, then what's the fun in all that? You learn as you go.
NeoToxicBlitz: I'm sure 'jman' didn't make that avatar either. I've seen many, many people having that same avatar over the several years. And the creator of that avatar appears to be Korean because at the end at a pause, there are three words written in Korean.
