High Difficulty mode (Limited-Time Mode) for all 3 stages are included after the normal 3 stages.
I got no damage from the enemy for the whole credit.
All dialogues are skipped.
I just concentrated on not getting damaged to complete all stages only.
I just used iPhone 6 Plus to record this video so please don't expect the quality so much.
