Hi there. About how long is the game? Can you adjust the difficulty? 360 Controller Support? Thank you!

https://www.youtube.com/watch?v=Dxd-t_yvRF0 It's the exact same game, I played it as a kid around 2001 on my Chinese knockoff NES that looked like a 2nd generation Genesis. The original was a really good game. I don't know if this is "stealing" the original game and I'm not accusing it, it's interesting to see the same old game for PC....
