I quickly realized that it is relatively hard to Google the name of this esoteric language, because the program consists only from punctuation characters which Google treats specially. However, I landed on this list of esoteric languages. Skimming over the list, I found the right language - (?!).
It was also hard to find the interpreter for this language, so I wrote my own decoder:
