I got one for you guys.

I remember when I was a kid, there was a game on the NES that I loved to play.

It was set in the sort of jarrasic era, it was a kind of an adventure shooter, you were this man that could shoot out of his mouth or something, the powerups included Ladders, other shots, and potions. the music was very nice. It was sidescrolling, back and forth. You could only go up so far without a ladder, but you can jump. Never beat it, and ive never played it since I was a kid. Oh, and you had to press SELECT to use a ladder. Good luck.
