Around 1 hour 16 minutes to beat. This game requires No Deaths (1 CC) to complete. There's no continues or extra lives. For that reason I dont include it in my 1 CC and No Death playlists, or consider it as an additional challenge to complete, just what the game requires.
Great game. I will definately review this one and post up a tutorial with commentary. I may try Hard mode too, if I dont have to grind in-game money to purchase it. This was the successful run. Beat it on my fourth full attempt with Shiro. I unlocked this character by beating The Conductor boss without taking damage, then defeating Shiro. Beating that fight No Damage unlocks the Shiro fight right away. Defeating him unlocks him as a playable character. He doesnt get as many special ability uses, but I really liked his bombs for doing huge boss damage and taking out tightly packed groups in the harder galaga style stages later on.
