Don't give up. There are plenty of options in front of you other than watching a Let's Play. Unlike other Sierra games, Quest for Glory is special in that you can replay the game with a different character class, and even if you've already played all three classes, you can always replay it with an hybrid class, like a mage with thief skills, a thief with mage skills, or optimally, a fighter with a sword and shield but also the skills from both the mage and thief classes (except Climbing), although I wholeheartedly suggest you finish the game once or twice with single character classes before attempting that because the three classes hybrid is a notorious jack-of-all-trades, master-of-none (early in the game you will suck at fighting, suck at sneaking, and suck at casting spells, not to mention all the money you will have to grind to buy all the tools needed to get decent.)
If you went with a fighter for you first playthrough, I can guarantee you will have even more fun as a thief or a mage because these two classes have more interesting sidequests and more interesting ways to tackle problems in the first two games. If you went for a thief on your first playthrough, go for a mage on your second, if you went for a mage on your first, go for a thief on your second. And If you're not too far from the end with your first character, you could always keep that savegame and, once you figure out how to solve all the remaining puzzles with your second character, you can always reload your first character and try to rush to the ending before Baba Yaga's curse times out.
But yeah, with old adventure games, especially Sierra's adventure games, remember to always save early and often and on different slots. With Quest For Glory I always found it preferable to have two or three save games that you overwrite all the time, but also have backup savegames made at the beginning of the day ("Morning Day 1", "Morning Day 2", etc.) that way, if you miss a timed event, you can always rewind to witness it, and even if you screw up badly, worse case scenario you will have to replay a day or two. And you have twenty game slots, don't be afraid to use them all.
