A fairly simple program can be written to decode the text. Code below

numbers = (23, 5, 12, 12, 27, 20, 8, 5, 27, 6, 12, 1, 7, 27, 9, 19, 27, 8, 9, 4, 4, 5, 14, 27, 8, 5, 18, 5, 27, 2, 21, 20, 27, 6, 9, 18, 19, 20, 27, 23, 5, 27, 8, 1, 22, 5, 27, 19, 15, 13, 5, 27, 20, 5, 24, 20, 27, 20, 15, 27, 3, 15, 14, 6, 21, 19, 5, 27, 25, 15, 21, 27, 14, 15, 23, 27, 20, 8, 5, 27, 6, 12, 1, 7, 27, 9, 19, 27, 9, 14, 27, 6, 1, 3, 20, 27, 19, 5, 3, 18, 5, 20, 19, 28, 1, 18, 5, 28, 8, 9, 4, 4, 5, 14, 28, 9, 14, 28, 20, 8, 9, 19, 28, 12, 9, 19, 20, 27, 4, 15, 14, 20, 27, 9, 14, 3, 12, 21, 4, 5, 27, 20, 8, 5, 27, 16, 1, 18, 20, 19, 27, 20, 8, 1, 20, 27, 1, 18, 5, 27, 19, 5, 16, 5, 18, 1, 20, 5, 4, 27, 23, 9, 20, 8, 27, 19, 16, 1, 3, 5, 19)

text = ""

for num in numbers:
    if num == 27:
        text += " " 
    elif num == 28:
        text += "_"
    else:
        text += chr(num + 96)

print(text)

Comments:

This problem is fairly simple but this technique of converting numbers to letters may be useful for many other crypto problems such as SquishedNumbers.
