Not sure which game you’re thinking about, there are lots of shitty Christian shovelware from that era, but Konami’s Noah’s Ark has nothing to do with it. And very few to do with the biblical story really.

I had that game on the NES (and I’m not in a Christian or religious family at all).

It’s a real game, the arcade-y kind that tries to kill you all the time. It’s quite hard.
