a game were you can kill or not kill and be killed by a bunch of monsters attacking you for seemingly no reason
by all means this game is FANTASITC 9999999/10 why? WHY? metta, mutable endings that aren't achieved by choosing a choice, and a skeleton that wont stop saying PUNS, oh yea and there is a bunch of characters like GOAT MOM, skeleton that has a kinda generic personality (oh god the fans are going to kill me) A TOO MAD TO DIE FISH woMAN , JUNK BOT, GOAT KING, goat kid, GOAT GOD, and another human that only appears in geocide, OH AND SPEACKING OF GENOSIDE (i meant to spell it wrong) there are two MAJOR ENDING pacifist and GENOSIDE ( i suggest you do genoside last because once doing this one you cant get pacifist ever again) pacifist is were you befriend EVRYONE including GOAT MOM (or don't and murder her without any guilt) THIN skeleton (or don't and get a clean head shot) TOO MAD TO DIE FISH woMAN (or don't and witness her true form and get and tripled amount of beat ups per second) JUNK BOT (or dont and wittiness her TRUE NEO GENERIC FORM that is pretty weak) and pun SKELITON (or dont and M E G O N O V A N I A) and that pretty much it

A small indie game with on of the worst communities that will harass youtubers for playing the game their own way and harass other people because of fandom ships.
"Yo do you like Undertale"
"Yeah, but I hate the toxic and shitty fanbase"
