Sadly, the game mode is still a work in progress, and is sorta buggy in a few parts, or unbalanced. But you my friend, yes you, can help develop the game mode yourself! My Discord server based around the mode allows people to suggest new features and bosses, help balance existing bosses, and generally just enjoy the ride while it lasts; So I invite you to join, and help this idea come to fruition!
