This is a super charming little soundtrack! Your music is so fun to listen to, and it feels like you yourself had fun writing it, which is always an awesome thing to get from listening to someones music. My one note is think about your choice of instruments and how it contributes to the overall feel of your piece, obviously it isnt my work so we may just have different opinions but the Synth you use for Pure Imagination isn't necessarily something that I would pick for the same ideas, but I do completely understand if it fits your vision, this is more a subjective critique then anything else. Your choices all feel very purposeful so I imagine its something you like, and that I just dont really understand it, and thats okay!
Overall i still really enjoyed this and would absolutely play this game!! Well done <3
