Dude, that is messed UP

Not bad.

This story is well written and can show what consequences come from being able to relive the same moment over and over. The ending feels realistic because doing the same thing more than a thousand times will mostly lead to just giving up. Good job with that. Gaster in this story may be the most realistic characterization, mysterious and wise, but my only nitpick is that he talks too similarly like Sans. That's all I have to say.

This story fills me with determination! The theme of not giving up is always going to be a winner in Undertale fanfics, and I really enjoyed this story you put together, as well as Gaster's character and conversation with Frisk. And that was evilly clever, throwing in that theoretical bad ending. XD

Duuuuuuude, that's really sad ._.

And that's when this fanfic went from heartwarming to soul crushing. *claps*

I love how you made the personality of Gaster! :D its awesome! Also, I love the new twist you're putting into the UT story. Now...!ets see what comes next... ;)

Technically, the Bad Ending of your story is the correct one. After all, you can't get the good ending if you fight Omega Flowey...

This was great. Especially your interesting take on the whole situation with Gaster. I also liked the bittersweet ending. (Don't give up Frisk!)

Never saw Gaster depicted like this before. As a really chill mentor figure I mean. Most of the time it's sad cinnabun that needs to be saved or abusive mad scientist and needs to be dunked on. It's refreshing.

Aww, I was kind of hoping there'd be the happy ending with everyone saved and Frisk would turn around to "thin air" and be all like "I'll save you too" and save Gastor sdkehdhehdvasohfbd my fantasies sorry. That was sweet. :)

awesome story.
