MAAAAAAAN I was obsessed with this game when I was a kid. It wasn’t the first Game And Watch game I had (I think that was Greenhouse) but it was definitely among the first three, and I spent months playing it and slowly getting better and better. Even now I can hear the beep beep beep rhythm of the little handheld as I ferried dripping oil back and forth. I loved the two views the game had it made the world of Oil Panic seem much larger than it was, and felt such a thrill when I finally hit 300 points and scored a much-needed extra life.
Can’t remember if I clocked it though. Clocking a Game and Watch was what we did before Achievements.
