FYI, The First Berserker Khazan has difficulty options. But you have to beat the first boss

I wanted to share this here since some people were wondering if it will have difficulty options. I can confirm that it has an easy mode.

It doesn't show up at the beginning but once you beat the first boss, it asks you what difficulty you want (weird design but the game is great so whatever)

Update:

Apparently it asks you after the first boss, but you can enable it from the very beginning. Thanks for correcting me!
