Dusttale: Endgoal. A Flawless Genocide.

The endballs is real

There will be a port to Android

Alright. So a few things. Game looks pretty good. I love how you remembered that endgoal uses canon murder!sans. None of that copied abilities and red bones shit. Although there are some nitpicks.

In phase 1 sans does not dodge, he tanks your hits and uses items when running low on hp.

You should not have any items at all, because sans took them all. Instead add a mechanic where you have to steal items from him.

Phase 4 is no longer canon. I'm not sure what it's gonna be replaced with, or if it's even gonna have a replacement.

Murder!sans still has kr, so endgoal sans should too.

Maybe even add an ending where sans wins in phase 1 and 2. Something like a "give up" button for game overs that trigger a unique cutscene.
