Not the prettiest nor the most flashy game out there but it's so rare to see such an elaborate mystery in a jam that it's honestly refreshing. I must admit I couldn't solve it but I'm not sure if it's because my guess was wrong or because Derick is sometimes written Dereck.
Neat entry, I think having more clues toward the murder weapons, better sprite scaling (some pixels are obviously larger than other) and a longer loop for the music would have enhanced it greatly.
