Honestly, it was very refreshing to just listen to a "random" song like this, without having to imagine a theme or expect a progression. I like the simplicity of this, and actually, the themes follow each other up very nicely. They are all diverse yet don't sound off. Also, I love the acoustic guitar! Especially 1:30 onward, it sounds so good and the strumming is lovely (Musescore 3 only has 'arpeggios' which don't really sound like a strum). Great song to end with!
Oh, and I have to ask: did you let triangle be worth -1 coins because you ended up with 16 coins for your instrumentation and did not want to leave an instrument out? You're the boss after all! xD
