I hear you!
I think I'll modify the chase parts so they're not instant deaths o(￣┰￣*)ゞ
Regarding the labyrinth ruins: From what you said about the endings, I'm guessing you went for route B. In route A you have more time, so it's assumed you've already played that route before route B, so the shorter time is just to add a degree of difficulty
Thanks for the feedback!
