Post the Current "Retro" game you are playing.

SMB 2 really kicked your a**. Tougher levels, far more death drops, wind and finding warp tubes that actually send you back a few worlds.

Doki Doki Panic was what the US SMB 2 was a copy of. Essentially the same except the key guardian doesn't move until you're out of the key room, the characters are obviously different but have the same unique powers and the waterfalls move at seizure inducing speeds. The slot machine bonus screen is also plainer.
