The file to play the game is called "nw-app". it's an executable black icon. Sorry, I forgot to rename it when I updated the game.
i looked all over but i cant find it , i thought maybe it was hidden but its not that either, i downloaded that mac version and there i see some different " nw-app" thing , im on windows 10 so i dont think i could play a mac version ? the drawing/art from the screenshot looks beautiful even if i cant play it
