Wow, I didn't think you'd actually respond and fix it in only 3 hours! I've re-installed the game, and I can now say that I've been able to beat it in about ~20 minutes.
The riddle is now a lot easier to understand, and the second number lock puzzle took a while to get, but I finally understood that the red numbers matched with the card.
This game was really fun and the puzzles were the perfect balance between challenging and simple to understand. The tension of trying to make sure you left everything where it was as you sit in the bed was actually pretty scary! Amazing game, and I appreciate the update :)
