Thank you for the reference Supra! I'm glad you like the game!
To answer your curiosity, it doesn't have a second ending. I planned to make one but I figure out I already have no will to lengthen the game even that I already make the second ending images and short storyline. It also feels crap, because in second ending, you kill/ defeat all the creatures, the black box dissapear, you escape, and the black box preying at you.
Here I include the second ending image that I never add to the game.
