Arrow Keys to move, Z to jump, X to swing sword. Hold C 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.
The Hollow Empire is a game by... @TheHollowEmpire ! check out his stuff. He made the base for the game, so today I figured I'd make my own boss fight using it. The boss is the heretic heart. The core of the mysterious Heretics. The Heretic Heart was actually cut content from Silksong that probably never got past the drawing stage, so I gave it my own lore and twist on it. Enjoy!
