Did a Normal 1CC on my first attempt, to derust stages. (37 min) ---------------------------- Cleared Extra again. (33m) --------------------------- Lunatic attempts. Got to the final boss.
Got a Desperate (hardest difficulty) clear. The game has no continues. It also crashed before I could save the replay. (2h 16m) ------------------------- Cleared the extra on first try then did again a Lunatic 1CC without a crash.
Cleared the extra (for some reason it already was unlocked), but I have yet to do a 1CC on Lunatic, choked at the final boss. Your hitbox is straight up broken most of the times. Unfortunate. I'll get it regardless.
