Story- Basically humans vs monsters. Humans won and sealed them up in a mountain. The creator didn't feel like explaining so just search it up. (Im sorry) :)

You wake up in yellow flowers. sThe last thing you remember is that you fell down a hole in a mountain. Now you're here. You decide to get up and walk down a hallway. You see an opening where there is a flower named flowey that was alive.

Flowey-"Hi! Seems like you're new here! Let me teach you some stuff!" A battle starts.
