There are so many Easter eggs oml

if you choose frisk name it will change into hard mode

I know
And Chara/anything else is easy mode

I saw that but didn't know it was hard mode, I should try that

You can also try asgore, toriel, undyne

every boss monster name gets an easter egg, you just can't use it

gaster? well, you'll just have to see for yourself. (gaster one also translates over to deltarune)

the game won't let you type "gaster", if you do it you just go back to the intro

which qualifies as an easter egg, considering it requires a specific input, does something unusual, and is mostly secret

it kinda creepy for me
