harpoon gun
shaped more like a harpoon
grabs power ups slower, and from the tip of the harpoon
only uses energy on returning
doesn't have thrust if there is no mob target
tech: reticulum - make one more harpoon if there are mobs nearby that you are facing
I'm letting this stack to 9 even though it's silly cause that is n-gon's style
tech: ceramics now lets both harpoons and needles ignore shields
this was coded poorly so if shield bugs show up it might be from this
tech: fragmentation makes ~15% fewer nails for everything it affects
tech: filament gives 3% length per ammo (was 1%)
also length is capped at 75 ammo because after that it's just annoying
tech: unaaq is longer at low ammo but scales slower at high ammo
bugs
fixed laser collisions on player head when crouching
returned experiment gun and field circles
