It's a short but compeling game. You could probably compleat the game in about a day or two but whats the fun in that. Don't read into this game just play it. It may or may not be a game for you but for about 96-98% of the populatio that plays it probably still remembers this game and will probably always do (unless something as great as it comes out)
But seriously and im talking straight towards you whom is reading this (and probably screaming at my spelling) DO ABSOLUTLY NOT LOOK ON ANY VIDEOS, DISCUSIONS, FANMADE CONTENT OR OTHER UNDERTALE RELATED THINGS UNTILL YOU PLAY THIS GAME. I did and boy howdy do I regret doing that. SO yea just play it. PS if you dont like the game after the first try try one more and if still not it probably only costed about 7-8 euros if you bought it on a steam sale.
