Hey thanks very much, sounds cool! I liked the 'swung'/lofi rhythm hihats, that was cool to see :)
Yeah it's interesting for me too being limited to 4 notes per instrument for making music for the game. I sometimes have to split melodies between instruments things like that, and also the beat length can't be that long, however because the music comes in one layer at a time I feel like I can be a bit more dense with the instrumentation, as it's less overwhelming than hearing it all in one go... It's an interesting way to work! Also it's a bit less daunting than having to come up with a whole song with different sections etc.
