Is there more to Undertale?

Undertale, by Toby "Radiation" Fox was released not too long ago, just when 2015 was about to end, and has since quickly amassed an impressive fanbase, going as far as crowning itself with the "best game of all time" Gamefaqs award. The game is fairly good, but does it deserve such a treatment?

Many theories have since popped up, trying to explain the bizarre success of this game. People all over the Internet have presented theories that range from the mundane, such as the game being designed from the ground up to be a viral hit, to the absolutely paranoiac, such as a conspiracy by secret organizations to push the game as an example of progressivism in videogames, passing by pointing out the fact that Toby already had a small fanbase before releasing the game or simply that the popularity is the work of clever Internet trolls. But could there be more to it?

Warning: heavy Undertale spoilers ahead.

When we first boot Undertale, the game shows us a brief cutscene in which the player character is shown falling into a sinkhole, then it proceeds to ask us to input our name (which will come later into play).

After exiting the tutorial zone, we are greeted by Flowey, a cute Flower that will teach us the basics of the game. He will tell us that the heart we are controlling in that screen is in fact our SOUL, and that we may make it grow stronger if we eat "friendship pellets" that will augment our LOVE. After touching one of those "friendship pellets", we discover that they hurt quite a bit. Of course, Flowey is in fact a murderous maniac trying to teach us the mechanics of death, rather than helping. Luckily for us, a goat named Toriel repels him before we get hurt, and bows to sweetly take care of us during our stay in the Ruins.

..Well, I havent played this game yet, I bought it, but havent played it yet. Purely because I listened to some of the music on youtube from it and fell in love with it, dudes a good composer, really gets the feel of a fight and the story at that point and puts it into music form. Hopes and dreams/save the world is probably one of the best old-school 32 bit style songs I've listened to in a very long time

Now I'm questioning if I even want to play a genocide run. Sure theres the challenge, but I know what happens, and I'm totally not cool with quietly selling my soul for a game.
