Oh that was the test room you found xD I don't know why I programmed it to send you there, but thanks for reporting it!
As for the battle, I just went back and realized that I had those two enemies working in different conditions, causing both to disappear only if you talked with the first one, good catch!
Keep an eye out for the next update! I plan to show more of the story and deepen the combat system a bit more!
Thanks for playing and for the feedback!
