This is probably the first 2D platformer I ever played. I don't remember anything about it other than the yellow cartridge. At that point I had only ever seen 3D games like Mario 64 and Ocarina of Time and simple, abstract arcade games like Pac Man and Galaga. I probably just straight up couldn't tell what I was looking at. I love it. This and Pokemon Red were the first games to challenge me not on a mechanical level, but an artistic one.
