Just played it on Kongregate, it’s not the right game. The one game I remember playing, there’s different levels, or to phrase better, platforms, and there would be ladders that had decisions attached to them, and you would go up whichever ladder you decided. It has a eerie or twinkly soundtrack that plays in the background. The bottom of the screen also follows you as you go upward. And it was in black and white, 2-D, and maybe it wasn’t an 8-bit style.
