Phantom Blade Zero: Hellwalker Achievement

The problem

Devs y'all need to add a Hellwalker achievement. Just finished the game and busted my ass for 2hrs on the final boss (not the lady of the veil) Zuo Shang and some wimp will beat him on Wayfarer then get the same achievement as me. This is the true ending btw

What players suggest

No, you won't, because you can change the difficulty at anytime, so if people can just play the game to the bosses on easy mode to look for relics/farm, but switch to hellwalker/use broken builds and then back to easy, but finish the game on hellwalker, then it becomes moot point.

The game can be designed so achievement is ruined if you switch the difficulty. I played Slitterhead game, yeah you…
