Hey there, there's no build to download for the game.
are you not able to unzip the file and run the 'Krass-NG_Jam14.exe' ?
What file? https://gyazo.com/ee1bbb01ce0391c9f45177ecb0c1f2fe
lol, it seems like 5 AM me wasn't too bright and never uploaded the game, It should be fixed now.
Also, just a heads up, but there's a voice-over that contains some swearing in the game.
