Good grief, it has been nearly 2 years since I last submitted anything to Newgrounds! So it was about time I finished something for the Portal.

This sequel to the original Tails' Nightmare game, which (in my opinion) contains many improvements. Wall jumping and rail grinding are two new features I've added, and the gameplay itself is much smoother than the last. I also added enemies (which I for some reason didn't bother adding in the original game) and a variety of difficulty setting options.

With all that being said, I hope everyone can enjoy the game!

Wow, I was so freaked out, I found this corridor in one part of the game, so I went inside to see if there was maybe a power up or something in there, but there was a dead end. I tried to go back, only to find another dead end. I went back and forth for a while, when suddenly, I ran straight into the Tails Doll, he just came out of nowhere! Anyways, fun game, and great surprise corridor you put in there.
