Sir . . . I just did a run with 0 stat upgrades or equipment on normal and beat both the miniboss and main boss, you HAVE to be missing the side buttons that let you increase your stats and equip items, and like Chaotic bacon said, spacebar to dodge. And you can turn on auto-aim spells and normal attacks (with left-click, just in case you're really missing buttons) in the settings, otherwise, this is the hardest skill issue I've witnessed in my life. I don't think I've even died in this game before . . .
