Got all the 3 endings. It's a short, but fun game.
But I had to play the web version because the linux version doesn't work. I tried to launch the game through the terminal (with ./nw) and got a bunch of Fontconfig warnings and "Check failed: InitDefaultFont(). Could not find the default font"
Found this (old) link about the same problem on another game, can be helpful: https://steamcommunity.com/app/922710/discussions/0/1628538707063677167/
