You can use it safely as long as you've read the wiki. If you're trying to play unspoiled, it will kill you. (Unless you only carry it for desperate escapes, and that means you're not carrying a weapon, which has vastly broader utility.) I feel like it breaks two of my favorite things about Spelunky: one, that you usually know why you died and learn something from it; and two, that you can eventually work everything out without consulting the spoilers. Both of those things are big problems in a lot of serious roguelikes, IMO, and Spelunky handles them beautifully for the most part. (Speaking as someone who 100%ed the original PC version, and sank some hours into the Xbox version. I think, in the end, I'd gotten all the Spelunky I wanted from the original, and I wasn't a big fan of the music or art style in the update.)
