Very helpful feedback, most of which hadn't occured to me but I appreciate very much! I definitely intend on returning to this game after the jam, and implementing fixes for all of the points you mentioned. Bulk buying is a must, your health is indicated by the opacity of your cube but a more visual element would be nice, red pickups are definitely not my best idea haha, a way to skip the intro is 100% coming, maybe an upgrade that gives a temporary time multiplier to speed through the start? Adjustments for homing so it focuses bosses, an option for auto fire (good idea) and maybe add a trail to the baby worm. I really appreciate that you enjoyed my game so much to write such a detailed, helpful comment!
