Yooo!
I just played the first two stages of the demo and this makes me really happy. Your game reminds me so much of a title most have probably forgot about from the Dreamcast era (although there has been other releases since then,) Bangaioh! I loved that game so much, and this definitely carries its spirit! I love the "Ora!" word bubbles, too; that's a nice touch! I can't wait to buy your game!
