Did a lot of bug fixes for today's Bloodborne Kart dev post!
The Moon Presence in Phase 3 originally never attacked the player due to a bug with their AI's lock on function. This has now been fixed and she will now properly attack you.
I also added a jump pad at the top of the hill in the battle arena. It is actually unique in that it will simply impulse the player 'forward' relative to their own angle, instead of a dev specified direction.
