Now, I have to be honest and say that I've never played Donkey Kong Jr. before, but damn, it sure looks fun now. And this is the ONLY time where Mario's officialy the villain.
I also preferred this entry over the original. IDK why, but it did seem to be the easier of the two. I used to be able to play this for an hour without getting a game over, and that was as a six or seven year old kid! Ah...this brings back memories.
I like this one then the original too. I played this one a lot when I was younger the most difficult level I got up to was 13, my brother got up to 19. He was better then me, there is about 30 difficulty levels
