I did not see this until now, but it looks like recently the full game was made playable here https://poki.com/en/g/narcissus, though the full game is also available on iOS but not Android as of yet. The buy link for the game on pc/mac was taken down some time ago, circa.. 2016?

Edit: The buy link is back at https://alexvscoding.itch.io/narcissus as of octoberish of this year.
