Yeah, those ammo-collection noises were definitely enough to wake the stunned.
I remember for some reason on some old hardware I used years ago, the Soundblaster option was extremely
loud, so I always had to use Quiet Soundblaster.
My own personal misconceptions:
Keen 1: I thought the blue cities were some kind of giant seashells until I took a really good look a few years ago, and realised they were cities inside of force fields. And I still don't understand what that pink thing at the start of Capitol City is supposed to be.
Keen 2: I dunno what I thought the Vorticon Elders were, but I don't think I understood they were supposed to be Vorticons.
Keen 3: I thought the pictures of the The Grand Intellect in the Vorticon's homes was not a picture at all, but their pet octopus inside a fish tank.
Keen4: Sleeping slugs were definitely something entirely different. (I seem to very vaguely maybe remember my dad telling me that they were actually slugs, but I don't think I saw the similarity well enough to be convinced.)
Also the Perilous Pit was absolutely some kind of odd-shaped dirt cylinder jutting up at an angle out of the ground until I saw this thread; and it still is if I'm not focusing hard enough.
Also I sometimes thought the slugs had only one eye, because the pupils were so close together.
Keen 5: This one is pretty convoluted. I'd gotten to the final level, and could not figure out how to destroy the QED. I did everything I could think of, from shooting as long as I had patience to ("The help menu shows Keen shooting it, maybe that'll work. Hmm, maybe I just need more shots." Don't know how many times I used I+F10), to pogoing on it like the fuses, I may have even tried to get the Shikadi mine to explode on it but it didn't seem to want to go there.
This went on for a couple weeks or so, and one day I just abruptly closed the laptop in frustration and went to do something else. (It was, by the way, not one that stopped running when the lid was shut.) When I came back later, I was surprised to see "Congratulations! You have completed "Goodbye, Galaxy!"" (Obviously, a Shikadi Mine came and found me while I was gone.)
So for a long time I believed that in order to win Keen 5, I had to leave the computer alone for awhile. At least 15 minutes. And it was highly random whether it would work or not. (Sometimes, not understanding what was really happening, I left it in the menu, or a Shikadi Mine may not have been actively loaded/ they all exploded already/ I didn't open the door.)
I guess I was cured of it one day when I just so happened to look at the screen as a mine was exploding and broke the orb. I still find this whole thing to be hilarious.
Keen 6: Not exactly a misconception per se, but I was convinced, due to the presence of the specific variants of Bloogs, that the Blooguards must be the daddy Bloogs and the regular ones were the mommy Bloogs (and the Blooglets, of course, were their kids). Perfectly logical deduction for a seven-year-old's mindset, I suppose.
Also, not related to the games at all, but I just now realised "
" is supposed to be Keen with a white mustache and I've often thought it was a cat mouth or something. Just thought I'd leave that little misconception in there.
