The Hollow Empire - Boss 1/100 WASD to move, space to jump, j to swing sword. Hold E to heal. This will consume void charges, which are obtained through hitting the boss. If you don't have any void charges or are already at max health, you can't heal.
Hollow Knight for inspiration. By the way, it is highly recommended to scream the word "Shaw" when you beat this fight. Hollow Knight players will understand this reference.
