Solomon’s Key (NES)

Finally beat it last year after trying for 35 years. Such a good game. It’s one of my favorite games of all time. Action platform puzzle game. It has two endings, and there is zero chance you’ll get the good ending without a guide. Not to beat each puzzle room, but to find all the hidden items. You see, if you miss one, all the ones after that don’t appear! So hunting for them naturally is nearly impossible. It also has a secret continue mechanic, too, without which the game is also pretty much impossible.
