I just got to the Omega Flowey fight.

Naturally died horribly because I was too freaked out to process what the fuck was going on.

Please tell me I'm not the only one that noped the fuck out after dying. I don't want to go through all that again. I'm seriously sitting here staring at the icon and whispering, "No."

Yea once you beat him once, you never have to fight him again (unless you go the Genocide or Pacifist paths and then True Reset your data to play more). I think that once you battle him a few times and get past him he's not as freaky. It's really worth getting past though.

It just got so damn meta, with the whole breaking the actual mechanics of the game and then mocking the hell out of me when I died. It's like that, "Turn it off," rumor on the SMT cartridge -- shit like that actually scares me and it's so damn stupid.

I was already aiming for Pacifist, so I made sure not to gain any EXP or LV. I don't think I'd be able to do Genocide route in good consciousness, so at least I can avoid that.

Here's a list of most of the changes. I hear there's some that isn't covered here.

I have so many more questions now than ever.
Papyrus heavily implies that he would've used a Gaster Blaster on you for his special attack. Then what was the bone stealing about?
Why does talking to Clamgirl make a drawing appear in Sans' workshop?
Clamgirl was apparently talking about someone named Suzy. Who is Suzy? And why would she have anything to do with Frisk going to the underground?

I honestly don't know about the correlation between Clamgirl and the drawing, but goddamn does it hurt my heart all the same.

Over anything, though? I'm more amused by the changed Check notices. The Mettaton ones especially got me laughing.
