Such an absolute classic. My brothers and friends and I played this so much when we were kids that we had a notebook written up to overcome the game's "DRM", which required you to find a letter in a particular page/paragraph/sentence in the game's manual. You then drank the potion with the right letter floating over it. If you got the wrong one, you died and had to restart the game, but this was only at the end of level 1 so that wasn't a huge setback. Theoretically you didn't have this manual if you pirated it, but kids have nothing but time so our notebook ended up quite complete.

The first time we got to the skeleton that comes to life and fights you, my heart was absolutely pounding. I didn't expect that kind of thing from a game, and you walk past a few other skeletons that don't move at all so the game conditioned you to kind of ignore them or just treat them as part of the environment. And my god, the vertical chopping blades you have to carefully jump through...those things are brutal.
