Wow, this was A+!
There's so much unrecognized effort put into this. Okay, the intro was amazing. I especially love that you did it karaoke-style for us. It was amazing. Secondly, those voices sounded so much like the real thing. The voices for this are so talented. (Although, you can tell something was wrong with Ciel's mic.)
Okay, the story was easy to follow(in a good way). I don't think I played/watched any previous episodes of this series but I still knew what was going on. I love that it wasn't overbearing. And the gameplay was so fun. I know this got a few rewards but I think it's honestly worth more than what its getting.
Last but not least, the Sonic animation at the end was amazing. You're awesome at sprite animation and flash animation.
