Despite the ridiculous cover art, the game play was kinda fun. You essentially run around killing dinosaurs, although I can't much remember why...I think they took your food or something. You also had to collect bones, which you could then use to by some massive upgrades! This game had fun little cut scenes in between levels which showed you what was coming up in the next level which, for a 5 year old, were absolutely hilarious. A real downside to the game was the inability to save, if you died you'd go all the way back to start. Bignose was incredibly frustrating, but a lot of fun.
Another weird thing about the game was that the game itself was not the original Nintendo Gray, but instead, a shiny "gold" that you only ever see on a few other games. I would love to show you a picture, but none of the google ones do the game any justice and I'm too lazy to go grab my camera and take a picture of the game. So instead, I'll offer some video of the gameplay!
