Casual me; I hardly watch or play, and this is one of those case were something popular grab my attention.
Undertale is an RPG from Toby Fox Kickstarter.
LORE:
Long time ago, there were 2 dominant race; Humans and Monster.
One day their was a war breakout between the two; human defeated the monsters and then punish all in a underground world and sealed them with a magic spell. Anyone who climb the mountain from their banishment never return.
That were the game begin.
Gameplay:
You play as a young child trap in a hole filled with monster and you must go back to the surface without killing any monster.
You have the option to kill enemys, however people highly recommend not to fight or the plot will ■■■■■, making the gameplay much harder.
You can dodge attacks and choose whats the right move to proceed.
I have spoiled my self multiple time and all I can say to this game is it invoking tear-jerkers, nightmare fuel, and feels.
I remember it being at the end of the pacifist run.
oh, after some research, it seems toby used a similar expression, though that specific picture is of the [spoiler].
they are pretty much the same expression.
