I've been playing the Classic version of this for the GameBoy Advance recently, and managed to make it up to round 63. I have a video here: https://www.youtube.com/watch?v=VztkUBfB5fk
I was wondering what round everyone else has gotten to? It's pretty difficult past round 50! I understand after playing the original that it's even harder as you can't change direction after jumping...
So, what round have you gotten to?
