Weapon pickups. Progression!
At the end of this gif, you can also clearly see the new energy regain animation - which is a "fake bullet" that enemies "fire" on death that tracks the player with ludicrous homing properties and heals you on contact whether you're dodging or not. This is a lot more intuitive and nicer-feeling, (Even if you can't really see the graphic against the floor that easily right now...)
Which brings us to the next point: homing bullets. They're in and I've got a neat little setup that gives them a lot of granularity - anything from ludicrous Macross missiles that do hairpin turns in the air to chase their prey to a more subtle aim-assist. I just don't have any visual way to show that off apart from the health whatsit homing right now, sorry!
