Hey man, cool game! I found all 15.. I like the background music, the character, the puzzle, and such a simple story.
One thing that mesmerize me is the star! I've trying to animate pixel art for "blinking" star. But it didn't work. But you star animation is so simple and doable! I think I would like to follow the style of your star!
Btw, I'm curious how you create the sound effect? Are create the background music by yourself? If so, what program you used to create it? If not, where did you find it?
