Around 32 minutes to beat. This game requires 1 CC completion in arcade mode, as far as I can tell.
Lost continues edited out. No matter what you seem to start back at the first fight, though the background and enemy is random, so progress wasnt clear. It seems choosing the Revenge option after death just restarts you with the character you were already using but does not save progress. You have to complete somewhere between 8 and 12 stages straight to win. You have 5 lives for each battle, as does the opponent. Its an interesting One Strike mechanic where landing a single hit takes out the opponent.
