Man, those sprites are awesome! I would like to se more of course! No worries about putting you on the credits, I don't have problems with that whatsoever, and belive me, most of the classic DDragon gameplay is already present.
I cannot talk too much about what I have in mind, but all of those extra moves you have seen are combinatios between several buttons, so it's not a FFight clone anymore.
I really, REALLY love the series, I grew with it, so you can expect tons of hard work. I've also edited some enemies...I'm not a dedicated sprite editor, but I can get to work some stuff here and there, specially new stages. My little brother is also helping me with the game music, he's translating every single piece of DDragon music to sound like the SNES version synth, so spect to hear that as well.
You can contact me on
hishou_hakurei_q@hotmail.com or the official blog
www.singlungopenbor.blogspot.com for any kind of help. By the way, i'm not someone who likes to keep my work on hold until some piece of sprite/music/code is done, so, it's ok if you don't feel like helping at certain point, I'll keep working on this game 'till is done, so it's up to you

Thanks again!
