Dream Walk: I love your choice of instruments. The big synths do feel really dream-like and set the stage for the type of gameplay really nicely. The mallet instrument has a nice and simple soothing melody that would certainly support casual platformer gameplay.
Going Deeper: I can feel the worry arise in this track and the level intensity certainly seems like it would be higher here. The swing rhythm you use gives a coolness to the track that seems like enemies are getting stronger and more comfortable getting in your way.
Overall: Having these two contrasting tracks helps give a sense of the overall character of your intended game and I really like the dreamy atmosphere that progresses to darker emotions with more forward momentum. Would love to hear what other levels would sound like in this game! Well done - thank you for sharing!
