I followed the steps that the readme file told me to do.
wget https://github.com/fastrgv/AdaGate/releases/download/v6.1.3/ag15apr17.tar.gz
tar -xzvf ag15apr.tar.gz
mv agate adagate_install_directory
cd adagate_install_directory
./adagate_gnu
When the game starts, the first thing that I see is water. I tried to turn around to see if there's anything else, but the game doesn't react to the touch-pad nor the mouse, but I could turn with "A" and "D" keys. There was nothing behind me, just more water and the sky seems to be black(I couldn't look up because there was no key I found that rotated my view up and down.). I swam a bit with "W" and "S" keys and I could hear in some zones water splashing while I was swimming, but in others there was no splashing of water what makes me think that there is land, it is just not displayed, I also sank a bit when I swam in the zones where I could hear the splashing.
The output of ./adagate_gnu
