Gotcha! That lowers it down a bit -- do you recall if the forest background was on the darker or lighter side at the time? And what did the game do when you were looping?
(The "Soldier with Alarm" / first "Run!" text could appear on most forest levels because the alarm encounter is timed to happen after 7 turns of choosing a direction, which is why I ask about the brightness of the background as that would help me narrow down what "level" you were on)
Thanks for helping me out on this!
