The addition of the sound effects are really endearing ^^
each track has it's character and some are the best kind of cliché (the kind where you absolutely know that you didn't took it seriously and was in for the laugh too ^^)
the transition being baked into the music shows that you thought about the cohesiveness of this OST, also i want to celebrate your ability to create really effective melodies and to support their presence in the track !
It's really a nice little journey.
