If anyone's interested, I made an english Tutorial (sort of) for the game mechanics, open the Spoiler tab for it:
Anyway Ututuya, I know I'm late to the party, but I guess a huge "Thank You" for this game is in order: it's amazingly engaging, solid, polished and really well thought out in details.
You should advertise it much more outside Japan, I found out about it by a fortunate mistake, but there are no decent english sources; this game would be a huge success if it had more visibility.
Also, there's a program called Lunaport that allows online play for games developed with 2D Fighter Maker, but we need more players!
(I know you play it online through Windows Messenger, but I can't understand the japanese guide on your website)
Oh, and lastly, there's one most noticeable bug that I hope you'll fix in the next version: whenever you cross your opponent in the air, all your commands get inverted but your character won't turn around until he lands on the ground...this gets really confusing, and the AI seems to suffer from it as well.
Other then that, thanks again for this really awesome jewel of a game!
Edit: In case people didn't notice, the next version will be coming soon, as teased in the website:

Can't wait!!
