You can make Naija dash by left-mouse-clicking, or by pressing the space-bar. By pressing one of these two again, shortly after dashing, you can make Naija spin. You can also dash, and dash-spin, off of surfaces.
In Energy Form, you can charge a shot to release 3 tendrils of energy. If you release a charged energy-shot after dash-spinning, Naija will fire 4 tendrils of energy. Lastly, if you release a charged energy-shot after dash-spinning off a surface, Naija will fire 6 tendrils of energy.
