That's an interesting key bind setup. Feels very old-school so maybe I can add it as a bind preset!
The boss does come down after you deal with his ultimate attack properly for you to wack lol. But seems I may have made the summoned knights needing to be killed to spawn the bubble shield to block the big blast attack a little too vague to understand. The idea was to encourage the player to explore the fight as it went and discover the knights being spawned were more than just an annoyance, but actually a safety mechanic.
I really appreciate your time and feedback! Eager to try out those binds myself now
