The "unnecessary language" was quite humorous. But the people's voices are very annoying. Also, why do you spin the gun every time? I think it would be a lot better if you gave the chances of having the bullet in the chamber you're about to shoot. Like a 2 of 6 chance it's in the chamber.
It eventually gets to the speed where it is damn near impossible to hit the coin. If it were a little slower or takes a bit longer to get to that speed, it would be a better game.
