Wow, this really feels like an Extra stage! Yumeko's fight is fun, but it has some problems.
Her noncard is really fast, its hard to know where the knives are going, you might wanna slow it down just a bit
Her first Spellcard is fine, Her Second Spellcard is a bitch, the knives can get you easily because they move so fast. Thats about it, and increase the time inbetween Yumeko's explosion and the next wave of faeries, I game overed because I went up and got rammed by Faeries.
Other than that your Shinki Attacks are AWESOME!!
