STEP 1
Keep the first run focused on the story
Follow the on-screen objectives with your group. Keep audio or the available visual cues on so you can notice changes in the sequence.
STEP 2
Remember where the story branches
The creator advertises two endings. During your first run, write down any important choice and watch which badge appears at the end.
STEP 3
Change one choice on the replay
Replay from the start and try a different choice at the point you recorded. Avoid changing several choices at once if your goal is to find what affects the ending.
