Awesome looking game and good solid puzzles. I liked the bouncing ball thing, that puzzled me for a moment. I think maybe watch out for having too short of an audio loop, it can get irritating or distracting if the player hears the same few seconds over and over. Something more spacious might suit this a bit better since its very minimalist visually. Also found the controls way too sensitive
Also here's the game I did audio for if you wanted to check it out, thanks! https://itch.io/jam/gmtk-2020/rate/696287#post-1639104
