Thanks for a review!
I think cluttering is a part of experience as it (to me) reflects that weight of memories and the process of trying to think about something but being distracted by past thoughts. Might not be the best thing from a gameplay perspective, but I think it's a bit poetic :D And it was also done to motivate users to use "clear head" button
As for sounds, yeah, it was my first time doing my own music, so I spent 2 evenings just trying to figure it out haha So it would defenitely benefit from having more melodies, but I've only had time for this one
