Debug Defuser is an odd duck as far as puzzle games. How can I put it? You're playing a party game where you have to remember new rules, like a drinking game. You can only speak in a british accent. Then I'm going to make you run around and do memorization of numbers and incomplete mathematics in your head, all while avoiding enemies and keeping a visual map in your head like a cabby moving through the domain of Cthulhu. I worry that by my description, you may think that this game is somehow bad. Quite the opposite in fact! I think that if you find yourself playing this game, I would not suggest a notepad (Unless the game goes beyond five digit passwords) as it may hinder your absorption into the spirit of this madcap puzzler. Instead I would suggest you immerse yourself in the experience of being a frantic spy constantly dealing with world glitches doing mental math in your head as you rush through corridors and intimidate or dodge guards. Great game!
