Pattern-wise Original is a pretty significant jump compared to Casual. But the difficulty to 1cc the mode isn't that spiky since the game is more about resource management than pure evasion... which is would be pretty crazy to do without the bullet-slowing Power Up. Also very fun!
Leader C boosts DPS on all ships. Ideally you'll want to be very aggressive to be safe. Good offense is great defense!
In this run I did gather all 5 fairies, but the game didn't let me access the TLB. Seems like there is a Rank requirement, but not sure how much did I have to maintain, which would require a long time of training. Getting any hits will bring the Rank down.
