This game is a well crafted masterpiece.
The characterization of all the characters is spot on and I found myself blushing and connecting to the undertale cast before me.
I liked Undertake when it first came out, but I was never a massive fan of it. Yet this piece of fan media has touched me and ignited a love for it I don't think I had before.
You made an adult person blush over a cartoon skeleton like I was 14 again reading my first lemon fanfiction. That takes skill.
The writing was wholesome and made me feel like I was coming home.. I love all of them and they are my friends and family.

I played through the genocide run and it broke me. I tried to play through to get the good ending again and found myself emotionally devastated when Chara made me kill Sans.
I suspected something bad would happen because of my decision to give my soul to Chara to reset the world, but I didn't know that the price would never being able to be with my love again; doomed to kill him again and again.
It made me wish dearly I could undo everything I had done. To make everything right again and never again stray from my SOULmate.
I almost cried when I realized even after deleting and re-downloading the entire game - my old save was still in play.
Thankfully, I found instructions here to get a clean slate- if I couldn't have found that, I might have been in a foul state of mind all day.
I plan to play through at least one more time to Sans the ending he deserves.
PS I also like how Sans seems to like the player regardless of what their true soul is.
