Only people who have fought Sans would understand.

Yes

What second phase

unbased

Saying unbased is unbased

but you just said it

When he’s sparing you and tired, he begins the second phase. When the bone hovers the fight button, that’s the second phase

Thanks lol. Another indicator I guess is the flavour text "it feels like a turning point"

I think it's when he starts sweating

Remember son, dying is gay!

lol

And that is how Undertale: Hard Mode was born.

i read 2nd as two'nd

Never actually fought sans, only fought him in Undertale Gameboy Edition. Made it to something around the 5th attack of his 2nd phase.

Who the f*ck made a Gameboy edition for a game that released years after the Gameboy was discontinued

It's actually really good. Play it some time. On gamejolt, only works when downloaded.

I've fought Sans and watched many people fight Sans and there is no second phase

after middle point can be considered a second phase I guess, as he starts using different attacks
