Solution

Paying attention to the author’s emphasis on cases, there are multiple things that you can try out, such as considering only uppercase letters, or lowercase letters, and so on.

What you arrive to in the end, is treating them as binary digits. The solution simply requires you to treat an uppercase letter as a 1 and a lowercase letter as a 0. This leads you to a binary -

010010000110010101110010011001010010000001101001011100110010000001110100011010000110010100100000011001100110110001100001011001110010000001100010011100100111010101101110011011100110010101110010011110110100100101011111011011000110100101101011011001010101111101000010011000010110101101101001011011100110011101011111010011010110111101110010011001010101111101010100011010000110000101110100010111110101000001110010011011110110011101110010011000010110110101101101011010010110111001100111011111010010000001100101011000010111001101111001001000000111000001100101011000010111001101111001001000000011111100000

which in turn, translates to -

Here is the flag brunner{I_like_Baking_More_That_Programming} easy peasy ?
