Hey Justin,
Thanks a lot for your detailed feedback. Appreciate the nice words :)
The reason I left zoomed in view as default, because I thought screen elements could look too small on monitors with high DPI (high pixel density).
As for music or gameplay features (such as ship upgrades or different AI), unfortunately I didn't have time to implement it, as I focused on polishing the minimum gameplay I created. However, that's something I'll consider improving on post-jam :)
