Aw!Loved it!Is there any chance you are going to post some songs Hien?Not necessarily here - some sites are more appropriate for music, sometimes.
I'm learning how to play the Uke, and your voice is wonderful! ^^
The final release of the game will have the tracks available separately yeah! I'm no musician so I'm just bundling them with these, ahaha! The Uke is real fun! Good luck!
