The Title Theme is a great example of layering; starting off simple but gradually growing more detailed and rich as it progresses. Kudos on the production here, getting everything to seamlessly fit as it is gradually being added can be tricky but it is working really well here. As a whole it reminds me of something I might hear back on the early-to-mid PSX era, á la Croc or something similar.
Sleep and Dream plays even further into that vibe; loving the carry over of instrumentation here and the thoughtful approach of less-is-more at the beginning of this. Leaving space for the melody to breathe and then gradually grow more filled out is great. Having it strip back toward the end and function as a loop if necessary is great planning ahead.
Sunnybubble Island drives that Croc comparison in even more for me personally - game has a stellar soundtrack, varied and well thought out. This is no different - I love the island and tropical influence coming in full force here. Changing up the rhythm and pace around the half-way mark is great for preventing fatigue, and once again the set up for the loop is perfect.
Grandma's House has that gentle, soft approach that comes with writing something homely. Loving the use of mallet instrumentation as the primary driving force; turning the instrument itself into a motif. Nice and pleasant melodies here, particularly around that half-way point again; the extra lead tones in the background do a great job of embellishing the whimsy of this track.
The change of pace in Escape the Dream Eaters sets the tone immediately. Having a filter oscillate from opening and closing on the piano is a genuinely great touch here - feels like it is playing along the lines of trying to stay conscious and protect your dreams from being devoured. The rhodes(?) layer that is present at the beginning acts as a great contrast to the piano itself as it feels like a malicious lullaby, effectively having both the bespoke instruments 'fighting' one another.
Dance of the Ducklings has this 'cheeky' kind of vibe to it - I can't quite describe it. It's mischievous in a sense, but not maliciously so. Great idea switching up the rhythm in this one and leaning more into a waltz. The orchestration here is on point and there are a lot of great uses of differing articulations. I could imagine this functioning in a variety of games, and for some reason it actually gives me more of an N64 vibe than the others. (Granted the systems are mostly interchangeable but you get me)
The Ending Theme leaning back into the motif (in both senses of the word) is genius and the use of a familiar rhythm here does a great job of driving it forward whilst keeping it downtempo. The change of instrumentation and direction about a third of the way in was really cool and a nice throwback once again. This track is really going through the paces and exploring a lot. Great ending section here - brings it all home and wraps it up in a neat little bow.
All in all, fantastic job - super solid submission. Arrangement throughout is great; nice and varied, nicely orchestrated and well thought out. Production is on point, all the tracks feel cohesive and belong, and the use of motifs is really clever. Great work, this was a delight to listen to! :)
