Thanks for the feedback. Personally I like the held notes there, but I could definitely try some modulation (like some vibrato or panning movement) to make it more interesting. I just started using Chipsynth SFC and this is the first song I made with it, so I'm still getting used to the software.
I wanted the change to the stripped down part to feel sudden, but I could probably put some lingering reverb or delay on the notes from the previous section so they don't feel like they disappear too quickly. Thanks again for the feedback!
