It's impressive how you were able to use just 3 melodic voices to give an identifiable beat all without drums. The chords and melody used here are also very pokémon, it's a nice adaptation of the style. The section at 00:48 is great, the way the bass and top lead join together to make the syncopation add intensity to the song and make an effectively distinct B section. It'd be cool to hear this with the traditional Gameboy sounds, but I'd be lying if I said the default musescore sounds aren't charming.
