Well, consider your demo successful, because playing it made me want the full game a lot. I'll definitely follow you guys here and on Tumblr :D
The sprites were so adorable and dynamic, it was really impressive, kudos to the artist there. And the moving backgrounds and CGs worked really well with the rest of the game. I liked what little we got of Manta's dialogue too, very flowery and poetic, I love it.
I'll very much look forward to the full release!
