The music and art really take this up a lovely notch for a three-day jam cycle, makes it nearly worth playing again on its own. Admittedly, I did have issues with the hitboxes for enemies feeling a bit unfair at times, as bullets could hit them but they wouldn't disappear most of the time, which was frustrating. Power-up and score coins also were hard to distinguish from bullets at points. Perhaps a future update could change the shapes of those?
Regardless, this is a well-polished effort for a one-person team, you should be proud of yourself!
