Oh, weird, I was expecting the opposite of this thread. I really enjoyed this trial. I finished it on my first go, with 10 mins still on the clock.
There are things that could've been improved, I agree. It took me a bit of exploring to understand what I had to do, because the instruction was misleading. Also, there was no indication that you've cleared out the enemies with the broken magitek, so I was still mounted for a min before realizing I was done.
