Not that I want to insist and bother you but you may want to ask people who don't speak English very well then. They're the ones to have the most trouble with it. I've played the module some more and my success rate is still about ~70% at best. The other 30% is when I can't defuse the bomb at all. Don't get me wrong, I approve hard modules but I'm worried about rendering the entire bomb unsolvable because of one module on it. Maybe you could even add a tiny button that forcibly shuffles the recording at a cost of a strike, as a last-resort tool (while not shuffling it on an incorrect solution so that your initial gameplay concept is more intact).

@Rushin' Russian I'll ask other people what they think. I really don't want to change too much, but I'm willing to tweak some things. I'll ask other people what they think.

I really wish the module would pick a different recording on a strike or at least produce some sort of a hint (such as highlighting the incorrect digits for example). Since everything is set in stone by the time you start the bomb, this module alone can easily render your bomb totally unsolvable if English isn't your first language. I myself can't make out roughly a third of the recordings. Otherwise, I enjoyed the concept.
