Like this game has a few endings and things to do different, I dont want to maybe spoil you here...
However, in my all got to live happy. Somehow 1 didnt... But you cant do much about it :<

That's the ending I got, which still seems very sad.
I'd want to hug him and never let go. ;_;

Thats true :'3

I was happy when I did the True Pacifist run, though I wish you can save Asriel...

I was tempted to do the Genocide Run, but I just can't push myself to do it

I could never ever do to genocide run, that's seems the most heartless run to do, especially after the true pacifist run.
I wouldn't want to let go of Asriel.

Exactly. I wanna hold Asriel and not let him go.. <3

That was the game's biggest shortcoming IMO: You can't save everyone.

Second biggest shortcoming, I felt, was how the game always assumes the worst of you. It doesn't assume you're going to start over to try to save Asriel -- it assumes you're going to start over to try the genocide run.

And honestly, I don't see why either had to be the case; why you can't assure Asriel that you are going to try your best to save everyone, including him, nor why there isn't some way to actually do so. Even if it's something completely convoluted like doing so many pacifist runs in a row until the game itself gains sentience and is like "Ugh, fine. There, you saved everyone," it just feels incomplete without that possibility.

Well, at least there's the Dreemurr Reborn tumblr that has a different way to save him. That would be one way to never let him go.
And I just found out that Fangamer has a Toriel plushie. I just had to get one, so I did. I hope they will have plushies of Asgore and Asriel too. I'd be determined to get them, and the other stuff on there too like the Delta Rune and Mercy shirts. But if they seriously had an Asriel plushie I would never want to let him go at all.

The game punches you right in the feels with that true pacifist ending ;w;

Well, technically, (spoilers for those who haven't played Undertale yet) Asriel was already dead, so the fact that he was back long enough for him and the main character to meet at all is pretty good in my book. Not to mention that you saved him from being a sociopathic flower, and a megolmanic death-god thing.

It's still incredibly sad how he died too. That it was the human who wanted to get rid of humanity and Asriel stopped the human from carrying it out, getting gravely injured because of it. It doesn't make it much better.

And apparently Sans has been working on something in his shed.
