The file is written with Brainfuck, so I use the [online interpreter](https://www.splitbrain.org/_static/ook/)to deobfuscate it. ![image](https://user-images.githubusercontent.com/45068820/63651435-f2832b00-c77e-11e9-86e0-c752223257af.png)
The output is another esolang named [Malbolge](https://esolangs.org/wiki/Hello_world_program_in_esoteric_languages#Malbolge). [Decode](http://malbolge.doleczek.pl)it, I get a hex output -> hex2strings ![image](https://user-images.githubusercontent.com/45068820/63651456-16df0780-c77f-11e9-8eec-ff85c3eade4e.png)
