If it wasn't working for you locally in your mac, and you have docker you can do the following:

  docker run -it ubuntu bash
  apt-get update
  apt-get install wget
  wget https://github.com/vaniacer/piu-piu-SH/raw/master/piu-piu
  chmod +x piu-piu
  ./piu-piu

Controls are WASD for arrows and P for select or shoot.
