Based on what you said on your project page, I can relate to having trouble with creativity. One thing that helps me is setting a goal to learn something new. You could watch a tutorial on YouTube and make a song using what you learned from the video. Or you could try to copy an existing song. Or just explore on your own and make something new. Whether it’s weird or good, it’s still music.
Anyways, my favorite track is your version of the theme in Bedroom. The sounds you chose are perfect and the mix is great. You could add two extra chords somewhere in there, make that a separate section, and that could be a complete track. Good job with this soundtrack!
