Click for next slide Feel free to put ideas for my concept in the comments
SIDE ORDER SPOILERS BELOW! My idea so far is that it would play out like the Marina boss fight, except the boss (my OC) would be situated on a tower (first image). Searchlights (similar to Asynchronous Rondo) rotate on one part of the tower. Standing in front of these will trigger and attack (need attack ideas) Destroying the portals activates a ride rail and enables you to shoot the targets to fully extend it to the top.
