Nice little chill game. The aesthetic is really nice and the different sound work well together.
Very minor complaints is that the icons don't really match models, so sometimes I would use one but forget what colour icon it was and have to test them randomly to find it again. The placement hitbox should be taller so that when I try to replace a sound it's harder to miss since the models were taller than the hitbox. When you zoom out too much you can't really see the first track, would be cool if it were more visible so you could see your entire work.
Just repeating myself, these are very very minor complaints. The game looks cool and works really well.
Well done!
