First off, I love the "winding down" effects, definitely conveys the idea of time being altered in some way. The music overall is dynamic, interesting, and constantly adjusting to the different areas of the game you describe. That's where I would give my first critique - while these songs don't sound bad by any means, it's a little confusing to me that they are on the same track. "This Old Great Garden" feels like it should be three seperate tracks that are divided by each subarea that you described in that level. The track as it is feels more like it's timed to a cinematic cutscene rather than an area you are exploring in a game. This same issue reoccurs throughout the soundtrack in a couple spots, and while the music itself is fun and colorfully conveys the imagery of the different areas you described perfectly; it just doesn't seem to me that it matches up with the an open world game as it is. On "Time to Quest Through Time" the song picks up at the very end, and while I'm always a fan of a nice electric guitar riff, that section just seems unnecessary compared to the rest of the track and suddenly changes the vibe completely.
All of that aside, I hope I didn't come off as being harsh - there is a ton of creativity and good world building here, the effort spent working on the game behind the music is impressive and really helps bring your ideas to life. The quality of the music is great and it was a pretty fun listen, overall a very solid and polished sounding soundtrack!
